How to test vortex flowmeter

"Vortex Flowmeter" has always maintained its leading advantage in plug-in flowmeters with its unique advantages. The Verabar flowmeter is basically suitable for the measurement of all pipeline specifications on the site. The application on large-diameter pipelines shows more advantages. It is applicable to flow measurement of various liquids, gases, and steam, especially ultra-low temperature, high temperature, high pressure, and moist fluids. The measurement of the medium. However, at the same time of application and promotion, there are also problems in how to maintain. The following is a summary of the work and simple maintenance of vortex flowmeters before they are put into operation:

1. Check the installation status of “vortex flowmeter”: after completing the installation of “Vortex Flowmeter”, it must be carefully inspected, requiring firm welding, correct direction, and no leakage under test pressure.

2. Instrument calibration: read the manual of intelligent flow integrator carefully. According to the calculation book attached to “Vortex Flowmeter”, the parameters in the intelligent flow integrator are correctly set to ensure that the integrator can correctly calculate and display the flow. If you go directly to the computer, you need to set the input data format and the corresponding compensation within the computer. 3. The instrument wiring is correct: "Vortex Flowmeter" and the differential pressure transmitter, flow totalizer together constitute a measurement system, please check again, Correctly put into operation.

4. System warm-up: After the commissioning work is completed, the measured medium is filled with the process pipeline, and the “vortex flowmeter” is temporarily closed. At this time, the balance valve of the three-valve bank should be opened, the high pressure valve and the low pressure valve. Is off. Turn on the instrument and warm it up for 15 minutes.

5. System operation: After the preheating is completed, open the high pressure valve and low pressure valve of the three valve group, fill the differential pressure transmitter with the measured medium, open the drain valve after the differential pressure transmitter, and quickly discharge the dirty liquid or gas. Close the blowdown valve, and then close the balance valve of the three valve group, the transmitter will enter the measurement state, and the flow totalizer will also enter the working state, showing the media flow in the pipeline. At this point vortex flow meter can be used normally.
