Based on Faraday's Law of Electromagnetic Induction, a pair of electrodes is installed on the tube wall perpendicular to the measuring tube axis and magnetic field. When conductive liquid flows through the tube, it cuts the magnetic lines and generates an induced electromotive force (EMF), which is detected by the electrodes.

The sensor transmits the EMF signal to the converter, where it is amplified, filtered, converted, and digitally processed. The converter then displays the instantaneous flow and cumulative flow on a backlit dot-matrix LCD.

TECHNICAL PARAMETERS

1.The electromagnetic flowmeter sensor features a simple structure with no moving parts in the measuring tube and no components that obstruct fluid flow.

2.It can measure contaminated media, corrosive media, and liquid-solid two-phase flow.

3.During measurement, it is not affected by temperature, viscosity, density, or conductivity (within a certain range) of the measured medium.

4.The output is directly proportional to the average flow velocity and is independent of the flow state (laminar or turbulent) under symmetrical flow distribution.

5.With no mechanical inertia and a fast response, the flowmeter can measure instantaneous pulsating flow as well as flow in both forward and reverse directions.

6.Industrial electromagnetic flowmeters are available in a wide range of sizes.

APPLICATION FIELD

Electromagnetic flowmeters are widely used in industries such as petroleum, chemical, iron and steel, food, power generation, papermaking, metallurgy, water supply and drainage, petrochemical, and medical industries.
