WFD series smart electromagnetic flowmeter
product illustration
WFD series smart eletromagnetic flowmeter could measure the volume flow rate of the conductive liquid and serosity, widely used in the industries of chemcial, invironment protecting, textile, metallury,mine, medicine,paper,plumbing,food,sugar,brew etc.
Working principle
The working principle of the eletromagnetic flowmeter is based on the Farady law of electromagnetic induction. The inside lining of the measuring tube of the flowmeter is the insulant which is non-magnetic conduction alloy tube. The two electrodes is installed vertically with axial flow direction. The electrode tip is paralleled with the inner tube surface. When the magnet exciting coil underways square-wave pulse by two-direction, it will produce one magnetic field with a intensity of magnetic flux as B. At this time when there is one fluid with a certain conductivity flow through the measuring tube, the incising magnetic line of force responsively produce electromotive force E When the conductive fluid pass the tube with the inner diameter D with the average velocity of flow: V(m/s), there is existing one field with the uniform intensity of magnetic flux as B. So it could sense the electromotive force E which is vertcial with the electromagnetic dirction and flow direction.
