How to deal with electromagnetic flowmeter alarm fault

1. Causes of alarm failures of electromagnetic flowmeters

Electromagnetic flowmeters are used more and more widely in industrial production, but alarm failures sometimes occur. The main reasons are as follows:

1. Path failure: Due to water quality or foreign matter in the pipeline, the inner wall of the sensor pipeline is deposited or damaged. The damage will cause the signal to be unable to be transmitted, thus triggering the alarm.

2. The power supply voltage is unstable or trips: The electromagnetic flowmeter requires a stable power supply to ensure its normal operation. If the power supply voltage is unstable or trips, the electromagnetic flowmeter will alarm.

3. Internal failure of the sensor: Internal damage or aging of the sensor will cause inaccurate flow measurement or failure to work properly, causing an alarm.

4. Measuring pipeline leakage: Pipeline leakage will cause unstable flow, thereby triggering the alarm of the electromagnetic flowmeter.

2. How to handle the alarm failure of the electromagnetic flowmeter

When the electromagnetic flowmeter alarms and fails, you can handle it from the following aspects:

1. Check the power supply Is the voltage stable? If the power supply voltage is unstable, you can solve the problem by replacing the voltage regulator or checking the power line.

2. Detect whether the sensor pipe is damaged: If the inner wall of the sensor pipe is deposited or the pipe is damaged, the pipe can be cleaned or replaced.

3. Check whether the sensor is aged: If the sensor is damaged or aged, it is recommended to replace the sensor.

4. Detect whether the pipeline is leaking: If the pipeline is leaking, it needs to be repaired in time, and the electromagnetic flowmeter must be recalibrated after repair.

3. Solutions for electromagnetic flowmeter alarm faults

Different solutions can be adopted for different fault causes:

1. Path failure: Clean the pipeline If there are deposits on the inner wall, replace the damaged pipe and recalibrate the electromagnetic flowmeter.

2. The power supply voltage is unstable or tripped: Replace the voltage regulator or check the power line to ensure that the power supply voltage is stable.

3. Internal sensor failure: Replace the sensor and recalibrate the electromagnetic flowmeter.

4. Measure pipeline leaks: Repair pipeline leaks in time, and recalibrate the electromagnetic flowmeter after repair.

In summary, when the electromagnetic flowmeter has an alarm failure, it needs to be checked and processed according to the specific situation, and corresponding solutions must be taken to ensure that the flowmeter works normally.
