Why does the vortex flowmeter have no flow display?

Many owners who use vortex flowmeters occasionally encounter vortex flowmeters without flow display, and give the following treatments for this situation:

1. Confirm whether the vortex flowmeter is connected to the power supply, check whether the voltage of each output of the power circuit board is normal, or try to replace the entire power circuit board to judge whether it is good or bad.

2. Check if the cable is intact and the connection is correct.

3. Check the direction of steam flow and whether the liquid in the tube is full. For the forward and reverse measurement, if the direction is inconsistent, it can be measured, but the set display flow does not match the positive and negative directions and must be corrected. If the sensor is too large, you can change the direction of the arrow on the sensor and reset the display meter symbol. If the pipeline is not filled with liquid, it is mainly caused by improper installation position of the vortex flowmeter. Measures should be taken during installation to avoid causing the liquid in the pipeline to be unsatisfactory.

4. Check whether the electrode on the inner wall of the transmitter is covered with a liquid crust layer. For the measurement steam that is easy to scab, it should be cleaned regularly.
