Precautions for the use of vortex flowmeters

Abstract: The information on the precautions for the use of vortex flowmeters is provided by excellent flowmeter and flowmeter manufacturers. 1. Inspection before power-on and flow-through after on-site installation 1) The flanges, valves, pressure measuring holes, temperature measuring holes and joints on the main and bypass pipes should be free of leakage; 2) Whether the vibration of the pipeline meets the requirements of the manual ; 3) Whether the sensor is installed correctly, each. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article on the precautions for the use of vortex flowmeters. 1. Inspection before power-on and flow-through after on-site installation 1) The flanges, valves, pressure measuring holes, temperature measuring holes and joints on the main and bypass pipes should be free of leakage; 2) Whether the vibration of the pipeline meets the requirements of the manual ; 3) Whether the sensor is installed correctly and whether the electrical connection of each part is good. 2. When the power is turned on for static debugging, the converter should have no output when the power is not flowing, the instantaneous flow indicator is zero, and the accumulated flow has no change. Otherwise, first check whether the interference signal is introduced due to poor shielding or grounding of the signal line, or strong vibration of the pipeline. If it is confirmed that it is not the above reason, you can adjust the potentiometer in the converter, reduce the gain of the amplifier or increase the trigger level of the shaping circuit until the output is zero. 3. Through dynamic debugging, close the bypass valve and open the upstream and downstream valves. After the flow is stable, the converter outputs continuous pulses with uniform pulse width, and the flow indication is stable without jumping. Adjust the valve opening and the output will change accordingly. Otherwise, the potentiometer should be carefully checked and adjusted until the output of the instrument has neither false trigger nor leakage pulse. 4. Instrument coefficient correction The instrument coefficient of the vortex flowmeter is calibrated under laboratory conditions. When the working conditions deviate from the laboratory conditions, the instrument coefficient should be corrected. The above is the entire content of this article. You are welcome to inquire our flowmeter manufacturer. selection, quotation, etc. 'Precautions for the use of vortex flowmeter'
