How to Solve Common Issues of Remote Type Electromagnetic Flowmeters

Troubles & Solutions

Remote type electromagnetic flowmeters are widely used in industrial applications. Their design allows the transmitter and flow sensor to be installed separately, making them suitable for high temperature, high pressure or hazardous environments. However, some common problems may be encountered during use. The following are remote type electromagnetic flowmeter common issues and solutions. When encountering related problems, you can refer to the table below.

Troubles & Solutions

Table 1: Remote Type Electromagnetic Flowmeter Troubles & Solutions
Common Issues	Possible Causes	Solutions
Unstable output	Unstable flow field	Modify the pipeline or add a dummy sensor
	The liquid passing through the sensor contains gas or large solid blocks	Normal phenomenon
	Electrical connection is loose	Check the wiring and connect the wires properly
	Poor grounding	Connect the ground wire properly
	Electrode leakage	Repair the sensor
No output for liquid flow	The two core wires of the signal transmission cable between the sensor and the converter are reversed	Reverse the wire head
	Power supply is not connected or poor contact	Connect the power supply and ensure good contact
	Leakage from the sensor instrument pipe, shell, or end face	Repair the sensor
There is output when the liquid is not flowing	Open circuit in the signal transmission cable connection between the sensor and the converter	Connect the cable properly
	Open circuit in the signal cable connection to the electrode	Open the sensor and reconnect it
	Contamination or insulation layer deposition on the electrode surface	Clean the electrode surface
	Poor grounding or open circuit	Connect the ground wire properly
Excessive error	Zero point is too high	Readjust the zero point
	Not fully filled with liquid	Improve the pipeline conditions, the sensor is always filled with liquid
	Excessive distortion of the power supply	Improve the power supply conditions to meet normal operating conditions
	Poor grounding	Connect the ground wire properly
