electromagnetic flow meter characteristics

The measurement principle of the electromagnetic flowmeter is Faraday’s law of electromagnetic induction. It is an instrument that measures the flow of conductive fluids based on the induced electromotive force when the conductive fluid passes through an external magnetic field. The main components of the sensor are: measuring tube, electrodes, excitation coil, iron core and magnetic yoke housing.

Electromagnetic flowmeters generally operate normally for a long time without maintenance after installation, and then require maintenance and daily inspection. The electromagnetic flowmeter can not receive the signal or the signal is too weak is a small problem. So there is no surprise, carefully do the following steps can be solved.

Electromagnetic flowmeter selection principle:

The measurement of sewage by electromagnetic flowmeter generally does not require daily maintenance, but when the measured medium is easy to adhere to or scale the inner wall of the electrode and the measuring tube, it is necessary to regularly clean the inner wall of the measuring tube and the electrode, and be careful not to damage the flowmeter lining and the electrode.
