Possible causes of electromagnetic flowmeter no display include abnormal power supply, sensor line failure and display failure.
1. Possible reasons why the electromagnetic flowmeter has no display
1. Abnormal power supply of the electromagnetic flowmeter: The electromagnetic flowmeter requires power supply. If the power supply is abnormal, the flowmeter will not work properly. Therefore, the first step is to check the power supply of the electromagnetic flowmeter and determine whether the power supply is normal.
2. Sensor line failure: The sensor line of the electromagnetic flowmeter is a key part of connecting the electromagnetic flowmeter with field equipment. If there is a fault in the sensor circuit, the electromagnetic flowmeter will not work properly and there will be no display.
3. Display failure: The display of the electromagnetic flowmeter is a key part used to display the working status of the flowmeter. If the display is faulty, the electromagnetic flowmeter will not work properly and there will be no display.
2. Solution to electromagnetic flowmeter having no display
1. Check the power supply of the electromagnetic flowmeter: First, you need to check the power supply of the electromagnetic flowmeter to determine whether the power supply is normal. If the power supply is abnormal, the power failure should be repaired in time to ensure that the electromagnetic flowmeter can work normally.
2. Check the sensor line: Check whether the sensor line is faulty. If necessary, replace the sensor line or repair the fault.
3. Check the display: Check whether the display of the electromagnetic flowmeter is faulty. If necessary, replace the display or repair the fault.
4. Contact professional technicians: If the above methods cannot solve the problem, it is recommended to contact the electromagnetic flowmeter supplier or professional technicians and ask them to repair or replace it.
