Vortex flowmeter problems

Is it caused by unstable flow rate?

May I ask which company's vortex street is the poster using? Or does it refer to all vortex flowmeters? What is the measuring medium?

Because of its large flux, it is not easy to get jammed and does not require maintenance. Our factory uses many vortex flowmeters. However, during use, we found that vortex flowmeters are more susceptible to pipeline vibration. Even in the shutdown state, they still have a flow display and do not return to zero, causing the cumulative flow rate to be high. In addition, the vortex flowmeter is also affected by the installation position. Although our factory strictly followed the instruction manual for 20 days before and 10 days after installation, it still caused a large deviation. The flow deviation measured by 3 flowmeters in one reaction cycle reached 16%. Originally, we thought it was a problem with the instrument, so we removed it and returned it to the manufacturer for calibration many times. However, the result after calibration was still the same, which was useless.

Yokogawa's product measures hydrogen sulfide gas flow.

It may be caused by a voltage issue.

Does this happen often? If it happens often, check to see if there is anything stuck in the gap of the generator body.； The process may also affect ； More on-site information is needed to make inferences. : ), I am from Yokogawa.

Is this often the case or occasionally? Occasionally, it is difficult to judge. After all, the vortex street only measures the Karman vortex street, which is greatly affected by pipeline vibration. If it happens frequently, should you consider replacing the transmitter? It is not recommended to use V-cone for measuring hydrogen sulfide, but the backflush effect is okay. .

It's not regular, it just happens occasionally and there's no pattern. This has never happened before.
