Electromagnetic flowmeter FAQ
Electromagnetic Flowmeter:
Under normal circumstances, the user's fault will be reflected:
Zero drift
2. Measurement error
3. Inconsistent data
4.mA output problem
5. Power problem
The solution is:
1. The flow meter has zero drift, but the value is small: the sensor is not fully charged, the sensor is not zeroed, the small flow cutoff value is set too small, the zero temperature is different from the current temperature, the sensor installation stress is too large, the sensor front section or Rear-end valve leakage meter flow zero drift, the value is larger: zero adjustment error, serious dissatisfaction with the pipe state, sensor insulation down, wet terminals, the valve is not closed
2. The flowmeter has an error, and the error is basically constant: the calibration coefficient is wrong, the sensor corrosion or wear causes the calibration coefficient to migrate, and the zero point is incorrect.
The error is not fixed: the measured medium contains gas, the back pressure of the flowmeter is low, cavitation occurs, and the sensor or converter is damaged
3. The display of the meter is inconsistent with the control display:
6. The reason why the meter has no display or there is no display output may be:
Measure whether the user's power supply is qualified
Check the user's output wiring is correct, use a multimeter to measure the current output
Check if the fuse in the converter's movement is broken (IFC300 has two fuses, power and output insurance; IFC100 has one insurance)
Check whether the display screen and the movement of the movement are plugged in, or if the display is broken, there is a condition that you can try using a normally displayed screen, or get back the company test .
