For large diameter, plug-in flowmeter can save cost and simplify installation. However, not all electromagnetic flow meters can realize the real function, unless you know the following points of attention.

 Plug in electromagnetic flowmeter

About the use of plug-in electromagnetic flowmeter, we need to pay attention to some matters. Let's see.

1. Make sure the media is full. For electromagnetic flowmeter, the most basic requirement is the full tube of medium, which is directly related to the accuracy of measurement results.

2. Avoid interference. Electromagnetic flowmeter works according to Faraday's law of electromagnetic induction which is sensitive to interference. When installing, pay attention to the selected position without interference, so as not to affect the normal measurement of electromagnetic flowmeter. In addition, the flowmeter shall be grounded.

3. The converter and transmitter use the same phase power supply to avoid abnormal operation of the instrument caused by the phase difference between the detection signal and the feedback signal, and keep the transmitter away from all electromagnetic fields and vibration.

4. Prevent the scale layer on the inner wall of the transmitter tube from affecting the measurement accuracy. If the resistance of the oxide layer is too small, the electrode will be short circuited, resulting in a smaller or even lower flow signal. At the same time, the insulation lining in the pipe is damaged or propagated. The electrode short circuit on the measuring circuit board will be caused by long-term operation in the place where acid, alkali and salt are concentrated.

The above is what Shanghai Cixi should pay attention to when using the plug-in electromagnetic flowmeter? Hope to help you, if you still have related product problems, you can dial the page of the consultation phone! The company provides 24-hour service!
