Electromagnetic flowmeter use in the flow does not accumulate the problem, the reasons include the power supply and signal line connection error, poor ground connection, internal blockage and improper parameter settings.
1. Causes of problems
1.1 Incorrect connection of power supply and signal lines
Incorrect connection of power supply and signal lines of electromagnetic flowmeter will cause the flowmeter to work abnormally. Incorrect power connection will cause the electromagnetic flowmeter to fail to start up normally, while incorrect connection of the signal line will cause the signal transmission to be unsmooth, thus affecting the cumulative calculation of the flowmeter.
1.2 Poor ground wire connection
Electromagnetic flowmeters usually need to be grounded. If the ground wire is poorly connected, it will lead to unstable signal transmission, thus affecting the cumulative calculation of flow.
1.3 Internal blockage of the flowmeter
The pipes inside the electromagnetic flowmeter may be blocked by dirt or particles, causing the measurement accuracy of the flowmeter to decrease, thus affecting the cumulative calculation of flow.
1.4 Improper setting of flowmeter parameters
The parameters of the electromagnetic flowmeter need to be set according to different measurement environments. Improper settings may also cause the flow meter flow to not accumulate.
2. Solution
2.1 Check the power and signal cable connection
If the power or signal cable is incorrectly connected, you can reconnect according to the connection instructions. If the wiring is aged or damaged, the power or signal wiring should be replaced.
2.2 Check the ground wire connection
Poor ground wire connection will affect the signal transmission of the electromagnetic flowmeter, causing problems with the measurement data of the flow meter. You can check whether the ground wire connection is good and make adjustments.
2.3 Clean the inside of the flowmeter
If the internal pipes of the electromagnetic flowmeter are blocked by dirt or particles, the flowmeter needs to be cleaned or replaced.
2.4 Reset parameters according to the actual environment
In actual use, the environment of the electromagnetic flowmeter and the fluid to be measured are different, and the parameters need to be adjusted. You can refer to the equipment manual or consult the merchant's technical support to reset the parameters of the electromagnetic flowmeter to ensure the normal operation of the flowmeter.
3. Summary
The electromagnetic flowmeter is a commonly used flowmeter, but there may also be problems with flow not accumulating during use. When encountering this situation, it is necessary to conduct a comprehensive investigation to check the power and signal line connections, ground wire connections, whether there is any blockage inside the flow meter, whether the parameter settings are reasonable, etc., and adopt corresponding solutions according to different situations. Only by ensuring the normal operation of the electromagnetic flowmeter can it better serve industrial production.
