Description:
The magnetic flowmeter is a kind of measuring instrument based on Faraday law of electromagneticinduction,which can measure the volume flow of electrically conductive liquid ,seriflux and so on.The structure of flowmeter is simple, function is reliable because there are no transmission parts, the working lifetime is long. There is no mechanical inertia, fast response, excellent stability. It can be applied on automatic inspection adjustment and program process system..
It is applicable for various liquid,Slurry body,and it has been widely used in the chemical industry,papermaking,petroleum.
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
Due to its unique advantages, it is widely used in the fields of petroleum, chemical industry, steel, light industry, sewage processing, environmental protection, water conservancy project and pharmacy to measure the volume flow of the conducted liquid mediums, such as acid, alkali, salt solution and so on.
TF series electromagnetic flowmeter follow the Faraday law of electromagnetic induction. They can be used to accurately measure the flowrate of liquids which are electrical conducting, caustic, and mixed with liquids .They are widely used throughout industries of petroleum, chemical engineering, pharmacology, papermaking, electric power, environmental protection and so forth.
Electromagnetic flowmeter suits for all kinds of liquids’ flow measuring such as electronic conductivity liquid, mud and slurry etc. on the basis of its min. conductivity. The result cannot be affected by temperature, pressure, viscosity and density.
It can also be used for measuring corrosive material as long as the right material has been chosen for the lining material. Solid medium will not affect the result.
Flow sensor and intelligent converter compact or separately composes a complete flowmeter.
