flanged 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

Electrode material	Applications
Stainless steel SUS316	Applicable in water,sewage and corrosive mediums.Widely used in industries of petrol,chemistry,carbamide,etc
Stainless steel     covered with tungsten carbide	Applicable in mediums of no corrosive and low abrasion.
Hastelloy B(HB)	Having strong resistance to hydrochloric acid of any consistance which is below bioling piont.Also resistable against vitriol,phosphate,hydrofluoricacid,organic acid etc which are oxidable acid,alkali and non-oxidable salt.
Hastelloy C(HC)	Be resistant to oxidable acid such as nitric acid,mixed acid as well as oxidable salt such as Fe+++,Cu++and sea water
Titanium	Applicable in seawater,and kinds of chloride,hypochlorite salt,oxidable acid(including fuming nitric acid),organic acid,alkali etc.Not resistant to a pure reducing acid(such as sulphuric acid,hydrochloric acid)corrosion.But if acid contains antioxidant(such as Fe+++,Cu++)is greatly reduce corrosion.
Tantalum	Having strong resistance to corrosive mediums that is similar with glass.Almost applicable in all chemical mediums.Except for hydrofluoric acid,oleum and alkali.
Platinum-iridium	Almost be applicable in all chemical mediums except for aqua fortis,ammonium salt
