Electromagnetic flowmeter may meet the problems and solutions

Electromagnetic flowmeter is a kind of flow measurement equipment widely used in industrial production processes. Due to its simple structure, easy use, accurate measurement and other characteristics, it is loved by the majority of users. However, during use, we may encounter some problems that affect the normal operation of the flow meter. This article will introduce some problems you may encounter and their solutions.

1. Unstable measurement results

Cause of the problem: It may be caused by unstable power supply voltage, bubbles in the pipeline, turbulence of the medium fluid, etc.

Solution: Check whether the power supply voltage is within the specified range, rule out air bubbles in the pipeline, and try to install the flowmeter in a straight pipe section to avoid medium fluid disturbance.

2. The displayed value does not match the actual flow rate

Cause of the problem: It may be caused by sensor damage, converter failure, poor signal line contact, etc.

Solution: Check whether the sensor and converter are working properly, replace damaged parts, and check whether the signal cable connection is firm.

3. The measured value is too low or too high

Cause of the problem: It may be caused by inaccurate sensor installation position, inappropriate sensor sensitivity setting, or the inner diameter of the pipe is too large or too small, etc. .

Solution: Adjust the sensor installation position to ensure that the sensor is fully in contact with the measured medium, adjust the sensor sensitivity setting according to the actual working conditions, and select the appropriate pipe inner diameter.

4. The flow meter cannot start or stops working

Cause of the problem: It may be caused by power failure, damaged switch, loose terminals, etc.

Solution: Check whether the power line is normal, replace the damaged switch, and check whether the wiring terminals are tight.

5. The flow meter output signal is abnormal

Cause of the problem: It may be caused by internal fault of the sensor or converter, poor cable connection, output module failure, etc.

Solution: Check whether there is any damage inside the sensor and converter, replace the damaged parts, check whether the cable connection is firm, and replace the output module if necessary.

In the process of using the electromagnetic flowmeter, regular maintenance must be carried out to detect and solve problems in time to ensure the normal operation of the flowmeter. At the same time, it is also necessary to select the appropriate electromagnetic flowmeter model according to the actual working conditions to obtain better measurement results.
