Magnetic circuit systems: Mainly used to generate DC and AC magnetic fields. Electrodes: Electrode are used primarily to measure the flow signal generated by the flow of a conductive liquid. In fact, most of the electromagnetic flowmeters made in China are two measuring electrodes.

Electromagnetic flow meter are a specific system comprised by transmitter and converter, cable length, insulation issue, number of shielding layers, distributed capacitance and conductor cross-sectional area all affect the measurement result.

The working condition of water mag flow meter is terrible normally. Thus, it is necessary to select electromagnetic transmitter with appropriate protection class, preventing external dust and moisture to damage mag meters.

Recently, a sewer plant in South Korea purchased several large calibre split electromagnetic flowmeters for sewage flow measurement, 2 sets DN250, 5 sets DN300, 1set DN600 split electromagnetic flowmeter. The installation of the large-calibre electromagnetic flowmeter is relatively complicated.

What is an electromagnetic flowmeter? Electromagnetic flowmeters use Faraday's law to determine the flow of liquid in the pipeline. As a result, the flow of the conductive liquid through the magnetic field causes the electrodes located on the wall of the flow tube to sense a voltage signal.
