Electromagnetic flowmeter white screen does not display numbers

Case introduction

1. Check whether the circuit connection is normal

The white screen of the electromagnetic flowmeter does not display numbers, which may be caused by poor circuit connection. In this case, we need to check whether the circuit connection is normal. First, we need to check whether the power wiring, signal wire and ground wire are in firm contact, and plug and unplug again. Secondly, we need to check whether the circuit connection inside the electromagnetic flowmeter host is normal. If there is any looseness, it needs to be re-fixed.

2. Replace the sensor

If the circuit connection is normal but the white screen of the electromagnetic flowmeter still does not display numbers, you need to consider replacing the sensor. It may be that the sensor is faulty, causing the electromagnetic flowmeter to not work properly.

3. Recalibration

After replacing the sensor, we also need to recalibrate the electromagnetic flowmeter to ensure that it can accurately measure flow and output numbers. Before calibrating, we need to first understand the working principle of the electromagnetic flowmeter and the calibration method. Specifically, the calibration process needs to be carried out according to different models and specific measurement requirements. For details, you can refer to the electromagnetic flowmeter instruction manual and other related information.

4. Other possible reasons

The white screen of the electromagnetic flowmeter that does not display numbers may also be caused by other reasons, such as power failure, circuit damage, etc. At this time, we need to recheck each component and connecting lines, troubleshoot and repair.

In short, the white screen of the electromagnetic flowmeter that does not display numbers may be caused by a combination of factors. Each part needs to be carefully inspected to find out the problem and solve it in time. Through reasonable maintenance and use, we can ensure the normal operation of the electromagnetic flowmeter and ensure the safety and efficiency of industrial production.
