Flow meter

  Phenomenon Reason Treatment Measures The pipeline has a flow， meter without an output 1. The power supply is malfunctioning. 1. Repower or replace the power supply. 2. The power supply is not connected. 2. Turn on the power. 3. The connection cable is broken or the boundary line is wrong. 3. Rewire and check […]

Phenomenon Reason Treatment Measures Indicates zero or very small movement 1. The balance valve is not fully closed or leaking. 1. Close the balance valve and repair or replace it with a new one. 2. The high and low-pressure valve at the root of the throttling device is not open. 2. Open the high and

  Phenomenon Reason Treatment Measures No flow signal output from the meter 1. The flow meter power supply is not normal. 1. Check whether the output voltage of the power supply circuit board is normal. 2. The cable connection is not normal. 2. Connect the cables correctly. 3. Liquid flow conditions do not meet the

  Phenomenon Reason Treatment Measures No rotation of the waist wheel 1. Dirt-jammed pipes. 1. Clean pipes, filters, and flow meters 2. The liquid under test solidifies. 2. Dissolve the liquid. The pointer does not move or stop when the waist wheel turns 1. Meter head puller disconnected. Meter head transmission enters dirt. Remove the

  Phenomenon Reason Treatment Measures No flow signal output from the meter 1. The flow meter power supply is not normal. 1. Check whether the output voltage of the power supply circuit board is normal. 2. The cable connection is not normal. 2. Connect the cables correctly. 3. The liquid flow condition does not meet

  Phenomenon Reason Treatment Measures Instantaneous flow rate with constant maximum value 1. The cable wire is disconnected or the sensor is damaged. 1. Replace the cable or replace the sensor. 2. The fuse in the transmitter is burnt out 2. Replace the fuse. 3. Sensor measuring tube blockage 3. After unblocking, tap the sensor

  Phenomenon Reason Treatment Measures No display when fluid is flowing normally 1. Power cord, fuse, etc. have a break or poor contact. 1. Use an ohm meter to troubleshoot. 2. Poor contact inside the display. 2. Use the replacement “spare version” method to check. 3. The coil has broken wires. 3. Check the coil

  Phenomenon Reason Treatment Measures Float flowmeter pointer jitter 1. Medium pulsation. 1. Increase the damping. 2. Unstable air pressure. 2. Using voltage or current stabilization device. The pointer stops at a certain position and does not move 1. Open the valve too fast and the float is stuck. 1. Slow down the opening speed

  Phenomenon Reason Treatment Measures The rotor does not turn 1. Filter clogged. 1. Clean the filter. 2. Impurities enter the flowmeter to make the rotor stuck. 2. Check the filter for damage and clean the inside of the flowmeter. The rotor rotates normally but the counter does not count 1. Poor engagement of the

1. The transmitter is made of Cast Aluminum, the sensor guide pipe is made of stainless steel, and the flange and body surface are made of carbon steel. 2. Pressure can do national standards and also can do the America Standard, and Generally, 150 # and 300 # are most frequently made.  3. Transmitter protection level
