What is the reason for the split electromagnetic flowmeter having liquid flowing through but no flow display? Hello! There are only three situations like the one you mentioned. 1. If the actual flow rate is too small or not enough, the liquid in the pipeline does not overflow the electrode, so the flow cannot be detected The common reasons for electromagnetic flow meters not displaying are concentrated in four aspects: power supply, connection, converter, and sensor, which require targeted investigation. 1. To troubleshoot power issues, first confirm if the power supply has been interrupted, check the status of the power switch and fuse. If the fuse is found to be blown, it should be replaced to match the original specifications. Secondly, measure whether the power supply voltage is stable. If the voltage is too high or too low, it may trigger the equipment protection mechanism, resulting in no display. It is recommended to use a multimeter to verify whether the voltage meets the equipment labeling range. 2. Connecting the Fengzhen circuit and checking for loose cables or poor contact is a common problem. Focus on checking if the connecting cable between the sensor and the converter is securely fastened. If there are signs of detachment or corrosion, it needs to be unplugged or replaced. At the same time, check whether the wiring complies with the instructions, such as whether the power and signal lines are connected to the correct ports, to avoid equipment abnormalities caused by misconnection. 3. Converter function verification: Aging of internal components or program disorder of the converter may cause faults. The reset operation can be used as a preliminary treatment, and long pressing the reset button or power o

4. Causes and solutions of electromagnetic flowmeter faults
Common causes and solutions of electromagnetic flowmeter faults are as follows:
1. Abnormal power supply due to no flow signal output of the instrument: unstable output voltage of the power circuit board or abnormal power supply.
. Solution: Check if the voltage of each circuit on the power circuit board (such as ± 12V, ± 24V) is normal to ensure stable power supply. Reasons for cable connection problems: poor contact, open circuit or short circuit of signal cables or power cables. Solution: Reconnect the cable, check if the connector is loose, and confirm that the cable is not damaged. Reason for inconsistent liquid flow state: The liquid is not filled in the pipeline or the flow direction is incorrect, resulting in the inability to form effective induced electromotive force. Solution: Adjust the pipeline design to ensure th
