Measuring Principles:
The measuring principle of electromagnetic flowmeter is based on the electromagnetic induction law of Farady. The sensor is mainly composed of measuring tube with isolate lining, a pair of electrodes installed by penetration of the measuring tube wall, a pair of coils and iron core to produce working magnetic field. When the conductive fluid flows through the measuring tube of the sensor, the voltage signal in direct proportion to the average flow velocity of the fluid will be inducted on the electrodes. The signal is amplified and treated by the transmitter to realize various display functions.
 
Main Applications:
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 waste water, agriculture and irrigation, paper making, food and beverage industry and pharmaceutical industry.
 
Features:

--Large choice of liner materials suitable for drinking water, wastewater, chemicals and other liquids.
--Suitable for use in custody transfer applications.
--Measurement is independent of the flow profile.
--Abrasion and corrosion-resistant liners available.
--Electric conductivity of medium can be used for detection of product change.
--No additional pressure loss.
--No moveable parts and long working life.
--Two-way measurement system to detect the positive and negative flow.
--Site LCD displays instantaneous flow, accumulative flow, flow rate. 
--Various types provided according to specific conditions.
