Description
Technical Field
The utility model relates to liquid level display equipment, in particular to a double-display in-situ liquid level meter.
Background
For the level gauge arranged on the container, in order to ensure that the measured liquid level is as accurate as possible or can be calibrated, two or more level gauges are generally arranged, and only one level gauge can be arranged on equipment with low liquid level requirements or limited sites.
For the case of two or more liquid level meters, two liquid level meters are taken as an example, wherein one liquid level meter is usually a liquid level meter displayed in situ and used for reading observation during on-site inspection and detection; the other is usually a remote liquid level meter, which is used for remotely accessing a liquid level signal into a control room, so that the liquid level and the interlocking function performed by the liquid level can be displayed in the system conveniently. For example, CN216480912U provides a boiler water level detecting device, wherein a first measuring cylinder and a second measuring cylinder are adopted, the measuring cylinders on the unused side can be cleaned through switching use, and the water level can be judged through combined use and comparison.
However, for a few containers with only one in-situ level gauge, there is some inaccuracy in the measured container level by only relying on the level display of the one in-situ level gauge, and it is difficult to calibrate the in-situ level gauge in real time.
Disclosure of utility model
The utility model aims to solve at least one of the problems and provide a double-display on-site liquid level meter so as to solve the problems that a container for measuring the liquid level by only arranging one on-site liquid level meter in the prior art has certain inaccuracy and is difficult to calibrate.
The aim of the utility model is achieved by the following technical scheme:
a double-display in-situ liquid level meter comprises a liquid level meter and a pressure meter;
The liquid level meter is connected with the bottom of the container at the bottom end through a pipeline, and is connected with the top of the container at the top end through a pipeline;
the pressure gauge is arranged on a pipeline connecting the bottom end of the liquid level gauge with the bottom of the container.
The liquid level can be measured in two different modes by combining conventional liquid level measurement with pressure measurement, so that more accurate liquid level measurement can be realized through a single in-situ liquid level meter, and the liquid level accuracy requirement of a container with only one in-situ liquid level meter or only one in-situ liquid level meter can be met.
Preferably, the container is provided with a liquid level meter interface, and the liquid level meter is connected with the container through the liquid level meter interface.
Preferably, the liquid level meter interface is in flange connection with the pipeline.
Preferably, a valve is arranged on the pipeline.
Preferably, the valve is a ball valve.
Preferably, the valve flange is connected to the pipeline.
Preferably, the pressure gauge is connected to the pipeline through a tee joint.
Preferably, the tee joint is a reducing tee joint.
Preferably, the pressure gauge is provided with a liquid level scale on the dial plate.
The reducing tee is used for installing an on-site pressure gauge, and the quantity of the liquid level in the container can be known according to the pressure displayed on the pressure gauge, so that the liquid level on the on-site pressure gauge and the liquid level on the on-site pressure gauge can be mutually verified.
The reading on the in-situ pressure gauge is the relative pressure (relative barometric pressure), and the level h of the material in the container can be calculated according to the formula p=pgh (p is the pressure, ρ is the liquid density, g is the gravitational acceleration, and h is the tapping point to the liquid level). Then, the exclusive liquid level measuring scale of the material is stuck on the pressure gauge corresponding to the pressure value, and finally, the numerical value of the liquid level can be directly read on the pressure gauge.
Preferably, the liquid level gauge is vertically arranged, and the wall surface of the liquid level gauge is provided with liquid level scales.
The working principle of the utility model is as follows:
The liquid level meter and the container form a communicating vessel which can display the liquid level in the container; the pressure gauge measures the hydraulic pressure of the bottom of the container, and then the height of the liquid level in the container can be calculated through a pressure formula.
Compared with the prior art, the utility model has the following beneficial effects:
Through the combined use of the conventional on-site liquid level meter and the pressure gauge, the liquid level in the container is measured by the principle of the communicating vessel and the pressure measurement, and the measurement accuracy of the single on-site liquid level meter can be improved.
The pressure gauge measurement data can also be compared with the display data of the in-situ liquid level gauge, and the in-situ liquid level gauge on the container can be corrected under the condition that the second group of liquid level gauge is not applicable. In addition, for the measurement of the hydraulic pressure, under the condition that the liquid density (liquid type) is unchanged, the corresponding liquid level height can be calculated quickly, and the hydraulic pressure measuring device is high in accuracy and can be used repeatedly.
The pressure gauge has small space volume, can be connected to a pipeline for measurement, effectively saves space, and provides a new scheme for accurately measuring and correcting the liquid level gauges for containers with multiple groups of liquid level gauges.

Detailed Description
The utility model will now be described in detail with reference to the drawings and specific examples.
The construction of a single set of in-situ level gauges 4, as is currently used, is shown in figure 1, which is connected by a pipe to the side of the vessel 1. More specifically, the side of the container 1 is provided with a liquid level meter interface 2 at the top and bottom, respectively, and a liquid level meter 4 is also connected to the liquid level meter interface 2 (flange connection) at the top and bottom, respectively, by a pipe, and a valve 3 (ball valve, flange connection) is provided on the pipe for controlling the communication. The liquid level meter 4 is vertically arranged, and a liquid level scale for displaying the liquid level is carved on the liquid level meter.
However, the in-situ liquid level meter 4 with the structure has the defect of certain insufficient measurement accuracy; and the liquid level meter 4 is difficult to directly correct when being singly arranged, and can be completed by matching with external equipment.
Examples
A double-display in-situ level gauge 5, as shown in fig. 2 and 3, comprises a level gauge 4 and a pressure gauge 6;
The liquid level meter 4 is connected with the bottom of the container 1 at the bottom end through a pipeline, and is connected with the top of the container 1 at the top end through a pipeline;
the pressure gauge 6 is arranged on a pipeline connecting the bottom end of the liquid level gauge 4 and the bottom of the container 1.
More specifically, in the present embodiment:
As shown in fig. 2, on the basis of the existing connection structure of the single-set on-site liquid level meter 4 and the container 1, a pressure gauge 6 (relative pressure) is further added on the bottom connection pipeline, and the pressure gauge 6 is installed at the bottom flange interface of the on-site liquid level meter 4 through a reducing tee for measuring the liquid pressure at the bottom of the container 1, and further, the liquid level of the material in the container 1 can be calculated through a pressure formula of p=pgh. Wherein ρ is the density of the liquid and varies according to the liquid contained in the container 1; in order to make direct reading more convenient, liquids with different depths and corresponding pressures (when the density of the liquid is unchanged, the pressures and the depths are in linear relation) can be measured first, then a liquid level measurement scale special for the material can be designed on the pressure gauge 6, as shown in fig. 3, so that the liquid depths can be read directly like the reading pressure, and errors possibly caused by on-site calculation are avoided.
By the arrangement of the double-display on-site liquid level meter 5, on-site liquid level correction can be realized under the condition that the second group of liquid level meters 4 are not connected; and the liquid level data obtained by two groups of different measurement modes can be mutually compared and mutually verified, so that the accuracy of liquid level measurement is improved. In particular, for the container 1 with small space and only a single set of in-situ liquid level meter 4, the double-display in-situ liquid level meter 5 can meet certain accuracy requirements and correction requirements, and can expand the application range of the single set of in-situ liquid level meter 4.

It will be apparent to those skilled in the art that various modifications can be readily made to these embodiments and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty. Therefore, the present utility model is not limited to the above-described embodiments, and those skilled in the art, based on the present disclosure, should make improvements and modifications without departing from the scope of the present utility model.
