Summary

An electromagnetic flowmeter is composed of two parts- electromagnetic flow sensor and electromagnetic flow transducer.

The operation of an electromagnetic flowmeter is based on Faraday law of electromagnetic induction.The mainly parts of the sensor are: measuring tube,electrode poles,excitation coil,iron core,yoke and housing. The measuring tube of the sensor is a short alloy tube whose diameter is D, the inner suface of it has an insulating liner.Two electrodes are fixed in the measuring tube along with the diameter direction of it and they usually flush with the inner surface liner.When excitation coil pulsed by two-way square wave,there generates a working magnetic field with a flux density B in the vertical direction of the measurement axis.In the meantime,if some electrical conductivity liquid flows at an average velocity V through the measuring tube ,cuts lines of the magnetic field,there generates induced electromotive force E.Electromotive force E is directly proportional to the product of flux density B,measuring tube diameter D and average velocity V,that's: E BVD. Electromotive force E(flow signal) is measured by the electrodes and transmitted to transducer through cable.After the transducer handles the flow signal by magnifying it, the flow and total amount can be displayed,also will output pulse and analog current etc. The transducer of LDG type electromagnetic flowmeter has an intelligent indicator suggesting Chinese characters LCD display.
