Some suggestions for optimal use of gas precession Vortex flow meter

1.Standardizing the installation of gas precession Vortex flow meter

The conventional installation of flow meters requires straight pipe sections at the front and back, which must meet at least 5*D in front and 3*D in back (here D is the pipe diameter)

As shown in the figure, the front straight pipe section is equipped with valves and filters, which can be optimized. And the front and rear pipes need to be the same size as the flow meter.

2.The valve is too close to the flow meter. When the valve is opened, the medium rushes straight into the flow meter due to pressure, causing large vibrations during the process, affecting the normal measurement of the flow meter.

3.At present, the flow meter is powered by a battery, which causes the flow meter to automatically enter a low-power consumption mode, resulting in reduced measurement accuracy, and the measured value is inconsistent with the actual value. For more stable use and more stable effects, pleaseUse the DV 24V power supply selected originally in the design to replace the battery power supply, and switch to DC 24V power supply in the DIP switch.

4.Set a damping time of 3-5 seconds for the flow meter to average out the spikes.

5.Strengthen the fixation at the front and rear installation locations of the flow meter, and use thick rubber pads in the fixing gap to reduce vibration and co-frequency interference.
