Steps for static debugging of vortex flowmeter

Abstract: The step information of static debugging of vortex flowmeter meter is provided by the excellent flowmeter and flowmeter manufacturer and quotation manufacturer. Inspection and preparation before commissioning of vortex flowmeter After completing the mechanical installation and electrical installation, the installation quality should be checked before power-on commissioning. (1) All connections, flanges, valves, pressure measuring holes, temperature measuring holes, etc. on the main pipeline and the side pipeline should be well installed. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the steps for the static debugging of vortex flowmeters. Inspection and preparation before commissioning of vortex flowmeter After completing the mechanical installation and electrical installation, the installation quality should be checked before power-on commissioning. (1) All connections, flanges, valves, pressure measuring holes, temperature measuring holes, etc. on the main pipeline and the side pipeline should be well installed, the screws should be tightened, and the welds should be in good condition; (2) Whether the sensor is installed correctly, and the installation direction Whether it is correct or not, and whether the grounding is good; (3) After the above inspection and confirmation are correct, the power can be turned on, and parameters such as the meter coefficient can be set into the meter. Static debugging (1) Slowly open the upstream valve, close the downstream valve, the liquid flows into the measurement pipeline, the pressure in the pipeline rises to the working pressure, and there should be no leakage at each connection; (2) Turn on the power supply and check the rated value of the measurement working power supply And whether the ripple is normal, observe the static working conditions of the vortex flowmeter and the supporting instruments. The details are as follows: (1) The vortex flowmeter should have no output signal, the analog output signal should be 4mA, and the pulse signal output should have no square wave; The instantaneous flow indication is 0, and the cumulative flow should not change (2) If a pressure and temperature transmitter is installed, the pressure transmitter should output a signal corresponding to the working pressure; the temperature transmitter should output a signal corresponding to the temperature of the medium. If the output signals of the pressure and temperature transmitters are normal and the vortex flowmeter has output signals, the vortex flowmeter should be statically adjusted. (3) The static high speed of the vortex flowmeter. If the output signal of the vortex flowmeter is a 50Hz pulse signal or a current signal corresponding to 50Hz, this is a 50Hz power frequency interference signal, and the shielding and grounding of the instrument should be improved to eliminate the 50Hz interference. If there is a small unstable output signal, it may be that the valve is not completely cut off and there is flow leakage, and the valve should be checked and closed tightly; it may also be that the gain of the converter preamplifier is too high or the trigger sensitivity of the shaping circuit is too high, and the gain should be reduced And trigger sensitivity until the output is 0; it may also be caused by pipeline vibration, you can check the pipeline vibration, take vibration reduction measures, eliminate vibration interference, so that the output of the vortex flowmeter is 0 when it is static. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Steps for Static Debugging of Vortex Flow Meters'
