Flanged Magnetic Flow Meter Application

Flanged electromagnetic  flowmeter can be used to measure the volume flow of conductive fluid in a closed pipeline. It is widely applied in the flow measurement and control in the fields of chemical and petroleum industry, metallurgy industry, water and wastewater, agriculture and irrigation, paper making, food and beverage industry and pharmaceutical industry.

The premise of using Magnetic Water Flow Meter is that the measured liquid must be conductive. The conductivity of the liquid cannot be lower than the threshold, the lower limit. If the conductivity is lower than the threshold, it will cause measurement error until it can not be used.

It can be measured even if the value exceeds the threshold, and the indication error does not change much. The threshold value of general electromagnetic flowmeter is between 10-4~(5×10-6)S/cm, depending on the model. It also depends on the length of the flow signal line between the sensor and the converter and its distributed capacitance. The product manual usually stipulates the signal line length corresponding to the conductivity.
