Electromagnetic flowmeter flow reset to zero

　　1、 Cause analysis

　　Electromagnetic flowmeter is a flow monitoring instrument that can accurately measure the flow of various liquids and gases, but the problem of zero flow often occurs during use. The main reasons for resetting the flow rate of electromagnetic flow meters are as follows:

　　1. Poor connection: Poor connection of the electromagnetic flowmeter may cause unstable current, triggering flow reset.

　　2. Sensor malfunction: Electromagnetic flowmeter sensor malfunction is also a common problem. If the sensor is damaged or defective, it may result in inaccurate readings or zero flow rate.

　　3. Signal loss: The problem of signal loss can also cause the electromagnetic flowmeter flow to reset to zero. Signal loss may be caused by environmental interference, cable damage, or internal sensor malfunctions.

　　2、 Solution method

　　1. Check the connection: If the electromagnetic flowmeter experiences zero flow, first check if the connection is normal. Check if the cable connection and grounding are in good condition to ensure stable current.

　　2. Check the sensor: Secondly, it is necessary to check whether the sensor is damaged or defective. You can check and repair according to the troubleshooting methods in the electromagnetic flowmeter manual.

　　3. Calibration: If the reading of the electromagnetic flowmeter is inaccurate, calibration is required. The calibration method can refer to the calibration method in the electromagnetic flowmeter manual. Correct calibration can effectively solve the problem of zero flow in electromagnetic flow meters.

　　4. Replace the sensor: If the sensor is found to be damaged and cannot be repaired during the inspection process, it needs to be replaced.

　　3、 Precautions for use

　　1. Correct installation: Before using the electromagnetic flowmeter, it must be installed correctly according to the installation requirements in the manual. Improper installation can affect the effectiveness of electromagnetic flow meters.

　　2. Protective measures: Once the electromagnetic flowmeter is stopped, corresponding protective measures should be taken, such as installing the sensor in a waterproof box or covering it with plastic cloth.

　　3. Normal maintenance: Electromagnetic flow meters require regular inspection and maintenance, such as cleaning cables, sensors, and electronic controllers.

　　In short, resetting the flow rate of an electromagnetic flowmeter is a common problem, but through proper troubleshooting and maintenance methods, this issue can be effectively avoided. I hope the content introduced in this article can provide some help to readers.
