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.

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.
