Abstract
This invention discloses a method for rechecking an on-line flowmeter, first making zero adjustment to the recheck instrument, setting parameters to the displays of recheck instrument and the flowmeter respectively and using signal transmitting line of the recheck instrument and display of the flowmeter of measure their on line fluid flow, flow rate and related parameters independently then to compare and interprete the two values measured. If the interpreted values are the same that shows the flowmeter is correct, if not, the flowmeter is not correct and needs to be checked, so as to standardize the check of flowmeters.
Description
Technical field
The present invention relates to the method for calibration again of flowmeter on a kind of line, refer to the tester again after a kind of utilization is made zero especially, carry out the verification of the pipeline flowmeter on the line, make the verification of flowmeter be tending towards standardized method of calibration again.
Background technology
The industry of use traffic meter now, diversity, what various, as the nozzle of refuelling station, the vacuum fill production line of drink manufacturing industry ... or the like, and in order to reach the standard degree of flow, according to the regulation of ISO, all need carry out the work of verification again of these flowmeters at pipeline every year, to attain the accuracy of flowmeter.
The flowmeter verification mode of general pipeline removes flowmeter termly on pipeline, and the flowmeter of pulling down is delivered to specific office (office of tool public credibility) check; Yet, these flowmeters are removed, at first need earlier production line to be stopped, and empty the interior fluid of pipeline, thus, the degree of difficulty of not only dismantling this flowmeter is high, and is not easy to implement, and need expend the activity duration and the manpower of dismounting, simultaneously, make also production line interrupt, and then influence the job procedure of industry that the utmost point is not had an economic benefit.
Summary of the invention
In view of this inventor studies energetically, designs, and develops the method for calibration again of flowmeter on a kind of line finally.
It is a kind of so that the verification of flowmeter is tending towards the method for calibration again of standardized online flowmeter that fundamental purpose of the present invention is to provide.
Another object of the present invention is to provide a kind of and directly carries out the verification of flowmeter on pipeline, and verification mode is the method for calibration again of online flowmeter simply and easily.
For realizing above-mentioned purpose, the invention provides the method for calibration again of flowmeter on a kind of line, mainly in the flowmeter of installing a tool display for the pipeline appropriate location of fluid flow, this flowmeter is utilized electromagnetic principle to record flowing velocity, flow and the correlation parameter of this pipeline inner fluid, and measured numerical value is shown on the display of this flowmeter, and utilize again and again the perceptron of the signal transmssion line of tester to be arranged near on the pipeline of this flowmeter; Its method of calibration is able to be finished by the following step:
Step 1: the tester detection unit that delivers to the tool public credibility earlier does the correction check make zero again;
Step 2: respectively the display of tester and flowmeter is again carried out the setting of parameter value;
Step 3: fluid is imported in the pipeline, and so that the signal transmssion line of tester and the display of flowmeter carry out flowing velocity, flow and the correlation parameter measurement of fluid on the line again;
Step 4: the numerical value that the display of flowmeter is measured, with the interpretation work of comparing of the measured numerical value of tester again, if the numerical value of the interpretation of comparing is identical, represent that promptly this flowmeter is correct, if the numerical value difference of the interpretation of comparing, represent that then this flowmeter is inaccurate, and need carry out verification work.
Advantageously, this is utilized a feedback line to link between the display of tester and this flowmeter again, make the measured numerical value of this flowmeter, via this feedback line feedback to this again in the tester, and be able to and this measured numerical value of tester comparison interpretation of directly making comparisons again, if the numerical value difference of institute's interpretation, then can utilize this again tester this flowmeter is carried out verification work.
What below cooperate better embodiment of the present invention now graphicly further specifies as followsly, and in the hope of making the personage who is familiar with correlation technique of the present invention, the statement of De Yiben instructions is implemented according to this.
Description of drawings
Fig. 1: whole assembly schematic appearance of the present invention.
Fig. 2: checking process synoptic diagram of the present invention.
Fig. 3: the whole assembly schematic appearance of preferred embodiment of the present invention.
Embodiment
At first, please cooperate referring to Figure 1 and Figure 2, the present invention is mainly in the flowmeter 20 of installing a tool display 21 for pipeline 10 appropriate locations of fluid flow, this flowmeter 20 is utilized electromagnetic principle to record the flowing velocity of these pipeline 10 inner fluids, flow and correlation parameter, and measured numerical value is shown on the display 21 of this flowmeter 20, and the perceptron 32 that utilizes again and again the signal transmssion line 31 of tester 30 is arranged near on the pipeline 10 of this flowmeter 20, make this flowing velocity of tester 30 measured pipeline 10 inner fluids again, flow and correlation parameter, be able to the numerical value measured, the comparison interpretation of making comparisons with this flowmeter 20.
By the configuration of aforesaid tester again, please continue cooperate consult shown in Figure 2, the method for calibration again of flowmeter on the line of the present invention, its step comprises:
Step 1: the tester 30 detection unit that delivers to the tool public credibility earlier does the correction check make zero again;
Step 2: respectively the display 21 of tester 30 and flowmeter 20 is again carried out the setting of parameter value; Wherein, the parameter value of required setting comprises: the density of the caliber of pipeline, the material of pipeline, fluid, the quality of fluid, the proportion of fluid ... or the like;
Step 3: fluid is imported in the pipeline 10, and so that the signal transmssion line 31 of tester 30 and the display 21 of flowmeter 20 carry out flowing velocity, flow and the correlation parameter measurement of fluid on the line again;
Step 4: the numerical value that the display 21 of flowmeter 20 is measured, and with the interpretation work of comparing of the measured numerical value of tester again 30, if the numerical value of the interpretation of comparing is identical, represent that promptly this flowmeter 20 is correct, if the numerical value difference of the interpretation of comparing, represent that then this flowmeter 20 is inaccurate, and need carry out verification work.
Method of calibration of the present invention directly measures pipeline 10 with the tester again after making zero 30, and measure without other element, avoid the rate of flow of fluids in the pipeline 10 to be subjected to blocking up of element, and reducing speed, so the measured numerical value accuracy of tester 30 is high again.
In addition, because method of calibration of the present invention directly measures pipeline 10, the flowmeter of not only being exempted on the disassembling pipe 10 20 send the check of specific office, and is kept not interrupting of work, and then avoids the job procedure of the industry that influences, and guarantees the competitive power of industry.
