At present, the use range of the large-capacity storage tank gradually extends over various fields of petrochemical industry, aerospace and the like, and people sometimes pay attention to the storage capacity of the large-capacity storage tank and the corresponding volume of the storage tank (tank) at different liquid level heights. That is, the large-capacity storage tank in the general sense is only used for storing the medium, which can not meet the actual demands of scientific research and production, but the storage tank is calibrated to have metering properties after volume calibration, or scientific judgment is made according to the volume values of different liquid level heights, so that the development trend of the large-capacity storage tank is the current development trend.

However, due to the long-term use of the tank, deformation, tilting, etc. factors may occur, which may result in that the tank volume table obtained by the above method will no longer be accurate.

Based on the method, the embodiment of the application provides a storage tank volume calibration method, the volume of the storage tank to be calibrated is segmented, and each sub-volume segment is calibrated by utilizing a corresponding standard metering tank and a magnetostriction displacement sensor, so that the corresponding relation between different liquid level heights and volumes in each sub-volume segment is obtained, the accurate calibration of the storage tank to be calibrated can be realized, and the accuracy of the storage tank volume calibration is improved.

Referring to fig. 1, fig. 1 is a flowchart of a method for calibrating a tank volume according to an embodiment of the present application, including but not limited to steps S110 to S170.

Step S110, segmenting the volume of the storage tank to be calibrated to obtain a plurality of sub-volume segments.

In the embodiment of the application, considering that the volume of the storage tank to be calibrated is generally a large-capacity storage tank, the volume of the storage tank to be calibrated needs to be segmented first to improve the calibration precision. Specifically, in the process of segmenting the volume of the storage tank to be calibrated, the shape, the size and the like of the storage tank to be calibrated can be combined for segmentation. The volume of the storage tank to be calibrated can be determined to be divided into a plurality of sections according to the shape, the size and the like of the storage tank to be calibrated, and the volume capacity corresponding to each section of sub-volume section can be determined.

Referring to fig. 2, fig. 2 is an exemplary diagram of segmenting the volume of a storage tank to be calibrated to obtain a plurality of sub-volume segments according to an embodiment of the present application. As shown in fig. 2, the total volume of the tank 100 to be calibrated is V. The volume of the storage tank 100 to be calibrated is segmented from bottom to top to obtain V1, V2, V3 and … … Vn. Where v=v1+v2+v3+ … +vn.

And step S120, selecting at least one target standard metering tank for calibrating the target sub-volume section according to the shape and the size of the storage tank to be calibrated at the target sub-volume section.

In the embodiment of the application, after a plurality of sub-volume sections are obtained, each sub-volume section needs to be calibrated in sequence. During calibration, a standard metering tank for calibrating each sub-volume segment needs to be determined. Specifically, at least one standard metering tank can be selected for calibration according to the shape and size of the corresponding storage tank to be calibrated at each sub-volume section.

Illustratively, the standard metering tanks include standard metering tanks having capacity specifications of 200L, 100L, 50L, 20L, etc. It is therefore necessary to select one or more standard metering tanks of corresponding capacity specifications, depending on the shape and size of the corresponding tank to be calibrated at the sub-volume segment. Taking fig. 2 as an example, the volume in the subvolume section V1 is obviously changed by the liquid level height, that is, the corresponding liquid level height can be changed when the volume is slightly changed, and at this time, a standard metering tank with smaller volume specification is suitable for calibration. For example, a standard metering tank with the capacity specification of 20L can be selected for calibration. The corresponding shape of the sub-volume segment V2 is regular, so that the change of the volume due to the liquid level height is not obvious, that is, the corresponding liquid level height is basically unchanged when the volume is slightly changed, at this time, if the standard metering tank with the volume specification of 20L is continuously selected for calibration, the standard metering tank with the volume specification of 20L may need to be used for multiple times of metering and then poured into the storage tank to be calibrated for calibration, and the calibration efficiency is reduced. Therefore, according to the embodiment of the application, at least one target standard metering tank is selected for calibrating the target sub-volume section according to the shape and the size of the storage tank to be calibrated at the target sub-volume section, so that the calibration accuracy is ensured and the calibration efficiency is improved.

In the process of calibrating the storage tank to be calibrated, the accumulated continuous calibration is carried out on each sub-volume segment. Firstly, calibrating V1, after the V1 is calibrated, continuously calibrating V2 on the basis of the calibrated V1, after the V2 is calibrated, continuously calibrating V3 on the basis of the calibrated V2, and in this way, when the Vn is calibrated, the calibration of the volume of the storage tank to be calibrated is completed.

And step S130, injecting liquid into the target standard metering tank, and acquiring the standard liquid level height of the target standard metering tank under the standard volume and the current first liquid level height of the target standard metering tank through a first magnetostrictive displacement sensor, wherein the first magnetostrictive displacement sensor is arranged on a metering neck of the target standard metering tank.

In the embodiment of the application, after a target standard metering tank for calibrating the target sub-volume segment is determined, liquid is injected into the target standard metering tank. During the injection of the liquid, the standard liquid level height at the standard volume of the target standard metering tank can be obtained by a first magnetostrictive displacement sensor mounted on the metering neck of the target standard metering tank. Meanwhile, the current first liquid level height of the target standard metering tank can be obtained through the first magnetostrictive displacement sensor.

In the embodiment of the application, the fact that the liquid injection is controlled by opening and closing the switch valve in the process of injecting the liquid into the target standard metering tank is considered, so that the volume of the liquid injected into the target metering tank is difficult to be just the standard volume of the target metering tank. It is therefore necessary to acquire the current first liquid level of the target standard gauge tank by means of the first magnetostrictive displacement sensor to gauge the actual volume of liquid injected into the target standard gauge tank.

In the calibration process, water is generally selected as the liquid to be injected into the target standard metering tank in order to reduce the calibration cost. For the calibration result to be more reliable, other liquids besides water can be selected as the liquid for calibration, such as petroleum or other liquids close to petroleum.

The magnetostrictive displacement sensor mainly comprises a waveguide wire, a measuring rod, an electronic bin and a non-contact magnetic ring (provided with a permanent magnet) sleeved on the measuring rod. When the magnetostriction displacement sensor works, an electronic circuit in the electronic bin generates an initial pulse, the initial pulse is transmitted in a magnetostriction wire (also called a waveguide wire), a rotating magnetic field advancing along the direction of the waveguide wire is generated, when the magnetic field meets a permanent magnetic field in a magnetic ring, magnetostriction effect is generated, the waveguide wire is twisted, a strain mechanical pulse with a fixed speed V is generated, the pulse is sensed by an energy pick-up mechanism arranged in the electronic bin and converted into a corresponding current pulse (termination pulse), and the time difference T between the two pulses is calculated through the electronic circuit, so that the liquid level heights of a storage tank to be calibrated and a standard metering tank can be accurately measured.

And step S140, injecting the measured liquid into the storage tank to be calibrated, and acquiring the current second liquid level height of the storage tank to be calibrated through a second magnetostrictive displacement sensor, wherein the second magnetostrictive displacement sensor is arranged on the storage tank to be calibrated.

In the embodiment of the application, a certain amount of liquid is injected into the target standard metering tank, the liquid after metering is completely injected into the storage tank to be calibrated by the target standard metering tank, and then the current second liquid level height of the storage tank to be calibrated can be obtained by the second magnetostrictive displacement sensor arranged on the storage tank to be calibrated.

Step S150, calculating to obtain the current volume corresponding to the current second liquid level height of the storage tank to be calibrated according to the original liquid volume of the storage tank to be calibrated, the standard volume of the target standard metering tank, the standard liquid level height, the current first liquid level height and the metering neck indexing volume of the target standard metering tank.

In the embodiment of the application, since the liquid injected into the storage tank to be calibrated is metered through the target standard metering tank, the liquid volume injected into the storage tank to be calibrated can be calculated according to the standard volume of the target standard metering tank, the standard liquid level height, the current first liquid level height and the metering neck indexing volume of the target standard metering tank, and the current volume corresponding to the current second liquid level height of the storage tank to be calibrated can be obtained by adding the liquid volume injected into the storage tank to be calibrated to the original liquid volume of the storage tank to be calibrated.

It should be noted that, for the subvolume section corresponding to the bottommost portion of the storage tank to be calibrated, that is, the subvolume section V1, the original liquid volume of the storage tank to be calibrated at the beginning is 0, that is, before the storage tank to be calibrated is calibrated, the storage tank to be calibrated must be empty.

In one embodiment of the present application, referring to fig. 3, fig. 3 is a flowchart of a step of calculating a current volume corresponding to a current second liquid level height of a storage tank to be calibrated according to an original liquid volume of the storage tank to be calibrated, a standard volume of a target standard metering tank, a standard liquid level height, a current first liquid level height, and a metering neck indexing volume of the target standard metering tank, which are provided in the embodiment of the present application, including but not limited to steps S310 to S320.

Step S310, calculating to obtain the liquid volume injected into the storage tank to be calibrated according to the standard volume of the target standard metering tank, the standard liquid level height, the current first liquid level height and the metering neck indexing volume of the target standard metering tank.

In the embodiment of the application, the liquid volume injected into the storage tank to be calibrated can be calculated according to the standard volume of the target standard metering tank, the standard liquid level height, the current first liquid level height and the metering neck indexing volume of the target standard metering tank, and specifically, the liquid volume can be calculated by the following formula:

；

In the method, in the process of the application,indicating the volume of liquid injected into the tank to be calibrated, < >>Indicating the current first liquid level of the target standard measuring tank,/->Represents the standard liquid level of the target standard metering tank, < ->Represents the metering neck graduation volume of the target standard metering tank, < >>Representing the standard volume of the target standard metering tank.

Step S320, adding the original liquid volume of the storage tank to be calibrated and the liquid volume injected into the storage tank to be calibrated to obtain the current volume corresponding to the current second liquid level height of the storage tank to be calibrated.

In the embodiment of the application, after the liquid volume injected into the storage tank to be calibrated is calculated, the original liquid volume of the storage tank to be calibrated is added with the liquid volume injected into the storage tank to be calibrated, so that the current volume corresponding to the current second liquid level height of the storage tank to be calibrated can be obtained.

Illustratively, the sub-volume segment V1 is calibrated first. A standard metering tank with the capacity specification of 20L is selected, a certain amount of liquid is injected into the standard metering tank, the liquid level height of a first magnetostriction displacement sensor arranged on a metering neck of the standard metering tank with the capacity specification of 20L is read, and the V is injected into the standard metering tank through calculation ₁₁ L liquid, this V ₁₁ L liquid is completely injected into a storage tank to be calibrated, and the liquid level height of a second magnetostrictive displacement sensor arranged on the storage tank to be calibrated is read to be L1, so that the corresponding volume V when the liquid level height in the subvolume section V1 is L1 can be obtained ₁₁ 。

The metering neck indexing volume of the standard metering tank can be obtained by calibrating the metering neck of the standard metering tank.

In one embodiment of the present application, referring to fig. 4, fig. 4 is a flowchart of steps performed when the current temperature at the time of calibration is not the standard temperature, including but not limited to steps S410 to S430, provided in the embodiment of the present application.

Step S410, the current temperature is obtained, and the temperature coefficient is determined according to the current temperature and the standard temperature.

In the embodiment of the application, when the current temperature in the calibration is not the standard temperature, the influence of the temperature coefficient on the volume is required to be considered, and in order to ensure the calibration accuracy, the temperature coefficient is required to be considered in the process of calculating the volume, so that the temperature coefficient is required to be determined according to the current temperature and the standard temperature.

Step S420, calculating to obtain the liquid volume injected into the storage tank to be calibrated according to the temperature coefficient, the standard volume of the target standard metering tank, the standard liquid level height, the current first liquid level height and the metering neck indexing volume of the target standard metering tank.

In the embodiment of the application, when the current temperature in the calibration is not the standard temperature, the liquid volume injected into the storage tank to be calibrated is calculated according to the temperature coefficient, the standard volume of the target standard metering tank, the standard liquid level height, the current first liquid level height and the metering neck indexing volume of the target standard metering tank. Specifically, it can be calculated by the following formula:

；

in the method, in the process of the application,representing the volume of liquid injected into the tank to be calibrated. />Representing the temperature coefficient, wherein->，/>Indicating the current temperature +_>Indicating a standard temperature. />Representing the current first liquid level height of the target standard gauge tank. />Representing the standard liquid level of the target standard metering tank. />Representing the metering neck index volume of the target standard metering tank. />Representing the standard volume of the target standard metering tank.

Step S430, adding the original liquid volume of the storage tank to be calibrated and the liquid volume injected into the storage tank to be calibrated to obtain the current volume corresponding to the current second liquid level height of the storage tank to be calibrated.

In the embodiment of the application, similarly, after the temperature coefficient is considered and the liquid volume injected into the storage tank to be calibrated is calculated, the original liquid volume of the storage tank to be calibrated is added with the liquid volume injected into the storage tank to be calibrated, so that the current volume corresponding to the current second liquid level height of the storage tank to be calibrated can be obtained.

Step S160, updating the current volume to the original liquid volume of the storage tank to be calibrated, returning to inject liquid into the target standard metering tank, and acquiring the standard liquid level height of the target standard metering tank under the standard volume and the current first liquid level height of the target standard metering tank through the first magnetostriction displacement sensor until the corresponding relation between different liquid level heights and volumes in the target sub-volume section is acquired.

In the embodiment of the application, after the current volume corresponding to the current second liquid level of the storage tank to be calibrated is obtained by calculation, whether the target sub-volume section is calibrated is needed to be judged, if not, the current volume is updated to the original liquid volume of the storage tank to be calibrated, liquid is injected into the target standard metering tank in a return mode, and the standard liquid level height under the standard volume of the target standard metering tank and the current first liquid level height of the target standard metering tank are obtained through the first magnetostrictive displacement sensor until the corresponding relation between different liquid level heights and volumes in the target sub-volume section is obtained, namely, until the calibration of the target sub-volume section is completed.

Illustratively, during calibration of the sub-volume segment V1, the corresponding volume is V when the liquid level in the sub-volume segment V1 is L1 ₁₁ Thereafter, V is ₁₁ Updating the original liquid volume of the storage tank to be calibrated. Continuing to inject a certain amount of liquid into the standard metering tank, reading the liquid level height of a first magnetostrictive displacement sensor mounted on a metering neck of the target standard metering tank, and calculating to determine that V is injected into the standard metering tank ₁₂ L liquid, this V ₁₂ L liquid is completely injected into a storage tank to be calibrated, and the liquid level height of a second magnetostrictive displacement sensor arranged on the storage tank to be calibrated is read to be L2, so that the corresponding liquid level height in the subvolume section V1 is obtained when the liquid level height is L2Is of volume V ₁₁ +V ₁₂ . In this way, the correspondence between the respective different liquid level heights and volumes in the sub-volume segment V1 can be obtained.

When the sum of the current volume of the storage tank to be calibrated and the standard volume of the target standard metering tank is larger than the total volume of the target sub-volume section, the volume calibration of the current target sub-volume section is determined to be completed.

Step S170, updating the next subvolume section adjacent to the target subvolume section into a target subvolume section, and returning to the step of selecting at least one target standard metering tank for calibrating the target subvolume section according to the shape and the size of the storage tank to be calibrated corresponding to the target subvolume section until the corresponding relation between different liquid level heights and volumes in all the subvolume sections is obtained.

In the embodiment of the application, after the calibration of the target sub-volume segment is completed, the next sub-volume segment adjacent to the target sub-volume segment is updated to be the target sub-volume segment, and then the next adjacent sub-volume segment is calibrated according to the calibration mode of the target sub-volume segment until all the sub-volume segments are calibrated completely.

Illustratively, after the calibration of the sub-volume segment V1 is completed, the calibration of the sub-volume segment V2 is continued, and at this time, at least one target standard metering tank is selected for calibrating the sub-volume segment V2 according to the shape and size of the storage tank to be calibrated corresponding to the sub-volume segment V2. And calibrating the sub-volume section V2 according to the calibration mode of the sub-volume section V1. It should be noted that, when calculating the current volume corresponding to the current second liquid level height of the storage tank to be calibrated, the original liquid volume of the storage tank to be calibrated is the current volume corresponding to the last time when the sub-volume segment V1 is calibrated. For example, in the process of calibrating the sub-volume segment V1, the volume corresponding to the last calibration data is V when the liquid level height is L5 ₁₁ +V ₁₂ +V ₁₃ +V ₁₄ +V ₁₅ V is then ₁₁ +V ₁₂ +V ₁₃ +V ₁₄ +V ₁₅ Is the original liquid volume of the storage tank to be calibrated.

According to the embodiment of the application, the volume of the storage tank to be calibrated is subdivided into the plurality of sub-volume sections, and then the sub-volume sections are calibrated in sequence, so that the corresponding relation between the liquid level height and the volume is obtained, and the problem that the original volume table is not accurate any more due to deformation, inclination and other reasons of the storage tank can be effectively solved. For the original storage tank without the volume table, the volume table obtained by the calibration method is not influenced by the shape, the placement angle and the like of the storage tank, and the accuracy of volume calibration can be ensured.

According to the embodiment of the application, the sectional calibration of the volume of the storage tank to be calibrated can ensure that the corresponding relation between the liquid level height and the volume obtained by the calibration is not influenced by the shape, the placement angle and the like of the storage tank to be calibrated, and the accuracy of the volume calibration can be improved.

In one embodiment of the present application, referring to fig. 6, fig. 6 is a flowchart of steps performed after the measured liquid is injected into the tank to be calibrated according to the embodiment of the present application, including but not limited to steps S610 to S630.

Step S610, when the current second liquid level of the storage tank to be calibrated, which is obtained through the second magnetostrictive displacement sensor, is the same as the liquid level before liquid injection, the step S is to return to inject liquid into the target standard metering tank, and the standard liquid level under the standard volume of the target standard metering tank and the current first liquid level of the target standard metering tank are obtained through the first magnetostrictive displacement sensor until the current second liquid level of the storage tank to be calibrated, which is obtained through the second magnetostrictive displacement sensor, is different from the liquid level before liquid injection;

Step S620, calculating to obtain the liquid volume injected into the target standard metering tank each time according to the standard volume of the target standard metering tank, the standard liquid level height, the metering neck indexing volume of the target standard metering tank and the corresponding current first liquid level height when the liquid is injected into the target standard metering tank each time;

step S630, adding the original liquid volume of the storage tank to be calibrated after accumulating the liquid volumes injected into the target standard metering tank each time, and obtaining the current volume corresponding to the current second liquid level height of the storage tank to be calibrated.

In the embodiment of the application, the fact that the liquid level of the storage tank to be calibrated is not basically changed is considered to be the fact that when the capacity specification of the selected standard metering tank is smaller, the liquid which is metered by the standard metering tank is only injected into the storage tank to be calibrated once. For example, for a tank to be calibrated having a volume capacity of 1000L, the level of the tank to be calibrated may not substantially change when about 20L of liquid is injected at a time through a standard metering tank. In this case, the calibration can be performed only by selecting a plurality of metering and a plurality of injection methods without replacing the standard metering tank.

For an exemplary storage tank to be calibrated with a volume capacity of 1000L, a standard metering tank with a volume specification of 20L is selected for a certain subvolume section. At this time, when about 20L of liquid is injected into the storage tank to be calibrated through the standard metering tank, if the current liquid level of the storage tank to be calibrated is found to be the same as the liquid level before the liquid is injected, the liquid is continuously injected into the storage tank to be calibrated through the standard metering tank until the current liquid level of the storage tank to be calibrated is different from the liquid level before the liquid is injected. At this time, the volume of the liquid injected into the standard metering tank at each time is calculated according to the standard volume of the standard metering tank, the standard liquid level height, the indexing volume of the metering neck of the standard metering tank, and the corresponding current first liquid level height when the liquid is injected into the standard metering tank at each time. The current volume corresponding to the current second liquid level height of the storage tank to be calibrated can be obtained by adding the original liquid volume of the storage tank to be calibrated after adding the liquid volumes injected into the standard metering tank each time. For example, after 5 times of liquid is continuously injected into the storage tank to be calibrated, the liquid level of the storage tank to be calibrated is changed, and at this time, the calculated total volume of the liquid injected into the storage tank to be calibrated for 5 times is added with the original liquid volume of the storage tank to be calibrated, so as to obtain the current volume corresponding to the current liquid level of the storage tank to be calibrated.

In one embodiment of the application, after injecting the metered liquid into the tank to be calibrated, the calibration method comprises:

when the number of times that the current second liquid level height of the storage tank to be calibrated, which is obtained through the second magnetostrictive displacement sensor, is the same as the liquid level height before liquid injection exceeds a preset threshold value, a standard metering tank with larger standard volume is selected as a target standard metering tank for calibrating a target sub-volume section.

In the embodiment of the application, when the measured liquid is injected into the storage tank to be calibrated for a plurality of times, but the current second liquid level height of the storage tank to be calibrated, which is obtained through the second magnetostrictive displacement sensor, is the same as the liquid level height before the liquid injection, namely when the number of times that the current second liquid level height of the storage tank to be calibrated, which is obtained through the second magnetostrictive displacement sensor, is the same as the liquid level height before the liquid injection exceeds a preset threshold value, the volume specification of the selected standard metering tank is too small, and at the moment, the standard metering tank with larger standard volume is required to be selected as the target standard metering tank, so that the calibration efficiency can be improved.

For example, for the volume corresponding to the middle part of the 200000L oil tank, if a standard metering tank with a volume specification of 20L is selected for calibration, at this time, 10 times of liquid may be continuously injected into the storage tank to be calibrated through the standard metering tank, and the current liquid level in the storage tank to be calibrated still does not change. At this time, in order to improve the calibration efficiency, a standard metering tank with larger volume specification can be selected again for calibration. For example, a standard metering tank with a volume specification of 200L can be replaced as the target standard metering tank.

In one embodiment of the present application, referring to fig. 7, fig. 7 is a flowchart of steps performed after segmenting the volume of the storage tank to be calibrated to obtain a plurality of sub-volume segments according to the embodiment of the present application, including but not limited to steps S710 to S760.

Step S710, selecting a plurality of target standard metering tanks with different volume specifications for calibrating the target sub-volume section according to the shape and the size of the storage tank to be calibrated at the target sub-volume section.

In the embodiment of the application, after the volume of the storage tank to be calibrated is segmented to obtain a plurality of sub-volume segments, one target standard metering tank can be selected for calibrating the target sub-volume segment according to the shape and the size of the storage tank to be calibrated corresponding to the target sub-volume segment, and a plurality of target standard metering tanks with different volume specifications can be selected simultaneously. For example, standard metering tanks with volume specifications of 200L, 100L, 50L and 20L can be simultaneously selected.

Step S720, injecting liquid into the first target standard measuring tank, and acquiring the standard liquid level height of the first target standard measuring tank under the standard volume and the current first liquid level height of the first target standard measuring tank through a first target magnetostriction displacement sensor, wherein the first target magnetostriction displacement sensor is arranged on a measuring neck of the first target standard measuring tank.

In the embodiment of the application, when a plurality of target standard metering tanks with different volume specifications are selected for calibrating a target sub-volume section, a first target standard metering tank is selected from the plurality of target standard metering tanks with different volume specifications, then liquid is injected into the first target standard metering tank, and the standard liquid level height of the first target standard metering tank under the standard volume and the current first liquid level height of the first target standard metering tank are obtained through a first target magnetostriction displacement sensor arranged on a metering neck of the first target standard metering tank.

Illustratively, standard metering tanks with volume specifications of 200L, 100L, 50L and 20L are simultaneously selected according to the shape and the size of the corresponding storage tank to be calibrated at the target sub-volume section. At this time, a standard measuring tank having a volume specification of 20L is selected as the first target standard measuring tank from among standard measuring tanks having volume specifications of 200L, 100L, 50L and 20L. The liquid volume injected into the tank to be calibrated is then metered through this standard metering tank of volume gauge 20L. Specifically, a certain amount of liquid is injected into the standard metering tank with the volume specification of 20L, and the standard liquid level height of the standard metering tank with the volume specification of 20L and the current first liquid level height of the standard metering tank with the volume specification of 20L are obtained through a first target magnetostriction displacement sensor.

And step 730, injecting the measured liquid into the storage tank to be calibrated, and acquiring the current second liquid level height of the storage tank to be calibrated through a second magnetostrictive displacement sensor, wherein the second magnetostrictive displacement sensor is arranged on the storage tank to be calibrated.

In the embodiment of the application, all the liquid measured by the first target standard measuring tank is injected into the storage tank to be calibrated, and the current second liquid level height of the storage tank to be calibrated can be obtained by reading the value of the second magnetostrictive displacement sensor arranged on the storage tank to be calibrated.

Step S740, calculating to obtain the current volume corresponding to the current second liquid level height of the storage tank to be calibrated according to the original liquid volume of the storage tank to be calibrated, the standard volume of the first target standard metering tank, the standard liquid level height, the current first liquid level height and the metering neck indexing volume of the first target standard metering tank.

According to the standard volume of the first target standard measuring tank, the standard liquid level height, the current first liquid level height and the measuring neck indexing volume of the first target standard measuring tank, the liquid volume injected into the storage tank to be calibrated can be calculated, and accordingly the current volume of the storage tank to be calibrated can be obtained by adding the liquid volume injected into the storage tank to be calibrated to the original liquid volume of the storage tank to be calibrated. And the current second liquid level height of the storage tank to be calibrated can be obtained by reading the value of the second magnetostrictive displacement sensor arranged on the storage tank to be calibrated. Thereby obtaining the corresponding relation between the current second liquid level height and the current volume of the storage tank to be calibrated.

And step S750, updating the current volume to the original liquid volume of the storage tank to be calibrated, and updating other target standard metering tanks except the first target standard metering tank to the first target standard metering tank.

In the embodiment of the application, if the target sub-volume segment is not calibrated, the target sub-volume segment is required to be calibrated continuously. At this time, the calibration can be continued by selecting the same standard metering tank as the last time, or by selecting a different standard metering tank as the last time. When the standard metering tank which is different from the last standard metering tank is selected for calibration, the current volume is required to be updated to the original liquid volume of the storage tank to be calibrated, and other target standard metering tanks except the first target standard metering tank are updated to the first target standard metering tank.

In the calibration process of the target sub-volume section, whether the standard metering tank needs to be replaced or not, and what volume standard metering tank needs to be replaced can be determined according to the shape, the size and the like of the storage tank to be calibrated corresponding to the target sub-volume section.

Step 760, the step of injecting the liquid into the first target standard measuring tank is returned, and the standard liquid level height under the standard volume of the first target standard measuring tank and the current first liquid level height of the first target standard measuring tank are obtained through the first target magnetostriction displacement sensor until the corresponding relation between different liquid level heights and volumes in the target subvolume section is obtained.

In the embodiment of the application, after a new standard metering tank is replaced, the target sub-volume section is calibrated continuously only by the same calibration method as the first target standard metering tank. For example, a standard metering tank with a volume specification of 20L is selected from standard metering tanks with volume specifications of 200L, 100L, 50L and 20L as a first target standard metering tank, and after partial volume calibration is performed on the target sub-volume segment V1, a standard metering tank with a volume specification of 100L is selected from standard metering tanks with volume specifications of 200L, 100L, 50L and 20L for continuously performing volume calibration on the target sub-volume segment V1, the volume calibration is performed only by the same calibration method as that of the standard metering tank with the volume specification of 20L.

In the process of calibrating the volume of the target sub-volume section, if the standard metering tank is replaced, when calculating the volume of the liquid injected into the storage tank to be calibrated, the standard volume, the standard liquid level height, the current first liquid level height and the metering neck indexing volume of the standard metering tank after replacement need to be calculated according to the standard volume, the standard liquid level height and the metering neck indexing volume of the standard metering tank after replacement.

In the embodiment of the application, in the process of carrying out volume calibration on each sub-volume section, the standard metering tanks with different specifications are selected for metering and calibrating, so that the volume calibration accuracy of the storage tank can be ensured, and the volume calibration efficiency of the storage tank can be improved.
