Protection level: IP65, IP67, IP68 (optional)

 

Output signal: 4-20mA current output, 0-1kHz frequency output, unit volume pulse output

 

Power: 220VAC, 24VAC, 3.6V battery powered

 

Faults and troubleshooting of plug-in electromagnetic flowmeter

 

Fault 1: There is no output current after the power is turned on. Cause: The power is not turned on.

 

Removal method 1. Check if the fuse is blown 2. Check the power circuit wiring.

 

Fault 2: The current output is zero (4 mA) after the power is turned on. Cause: 1. The direction of the sensor mark is opposite to the flow of the fluid. 2. The converter excitation power line is connected incorrectly. 3. The input signal lines E1 and E2 are reversed.

 

Exclusion method: 1. Adjust the direction of the sensor to match the direction of the fluid. 2. Rewire the cable in the correct way. 3. Replace the signal lines E1 and E2.

 

Fault 3: The output signal fluctuates too much. Cause: 1. There is gas at the sensor electrode, which causes the electrode to be in poor contact with the measured medium. 2. There is accumulation on the surface of the electrode, and the electrode is in poor contact with the medium. 3. The media flow actually fluctuates greatly. 4. Poor grounding.

 

Discharge method: 1. Correct installation to eliminate the influence of gas in the pipeline. 2. Clean the electrode surface. 3. Increase the meter damping time.
