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.
