What are the common faults of vortex flowmeter? How to solve it?

2. How to deal with the display of overrange in a vortex flowmeter

The core solution for the display of overrange in a vortex flowmeter is to first troubleshoot temporary faults, then locate hardware or parameter issues, gradually solve them, and then restore normal measurement.

. 1. Temporary emergency troubleshooting steps: First, quickly deal with display abnormalities caused by exceeding the range to avoid affecting production or measurement. 1. Cut off the instantaneous flow signal: temporarily close the valve upstream of the flowmeter to stop the fluid flow, and observe whether the displayed value drops back to the normal range. 2. Restart the equipment: disconnect the power supply of the flowmeter, wait for 10-30 seconds, and then power it back on. Some false exceedance caused by signal interference will automatically recover. 3. Check the pipeline operating conditions: confirm whether there is cavitation, a large number of bubbles, excessive fluid impact, etc. in the pipeline, which can cause the instantaneous flow peak to far exceed the set measuring range. 2. Accurately locate the cause of the fault through conventional methods. Detect and confirm the specific causes of exceeding the range

1 Check the range parameters: Check the settings menu of the flowmeter to confirm whether the current configured range matches the actual pipeline flow rate. In some scenarios where the working conditions are changed later, there may be a mismatch in the range. 2. Check the sensor status: - Check whether the detection probe is covered by impurities or scaling in the pipeline, which affects the signal acquisition accuracy. -Confir

4. Investigate pipeline abnormalities: confirm if there is any blockage in the pipeline, pump equipment start stop impact, or valve misoperation causing a sudden increase in flow rate

3. Targeted repair plan: Solve the problem according to the identified problem

1. Range mismatch: enter the parameter setting menu of the flowmeter, adjust the upper limit of the range to 1.2-1.5 times the actual maximum flow rate, which meets the conventional margin requirements for industrial measurement

2. Probe contamination or looseness: After stopping the machine, disassemble the probe, clean the surface attachments with a soft cloth, and re fix it in place according to the installation mark, being careful not to damage the sealing structure of the probe

3 Electromagnetic interference or line failure: Replace the signal transmission line with shielded cables, stay away from interference sources such as high-power motors and frequency converters, and reconnect loose wiring terminals. 4. Abnormal pipeline conditions: Investigate and solve pipeline blockages, adjust valve opening to stabilize flow rate, install buffering devices to reduce the impact of fluid impact on measurement. 4. After subsequent verification and preventive repairs are completed, it is necessary to conf
