Electromagnetic flowmeter is based on Faraday electromagnetic induction principle to accurately measure the volume of conductive liquid total flow of the instrument panel.On the macro economy, the conductive liquid is regarded as the electric conductor, and the fluidity of hydrodynamics is regarded as the electric conductor for the fitness exercise of laser cutting magnetic induction line.In fact, using electromagnetic method to accurately measure the flow of conductive liquid water, its internal conditions are far more complex than the solid electric conductor in the electromagnetic field laser cutting field fitness exercise.
As a particle of indoor space, the vector material field of magnetic induction intensity is within the limited symmetry range, and the fluidity of conductive liquid is only the fitness movement of the particle in the continuous medium.The velocity of continuous media in the passage is vector material, and the velocity spread in the passage is also a complex problem.Only under certain necessary conditions can accurate reference answers be obtained for such complex problems.
Principle of electromagnetic flowmeter measurement
Electromagnetic flowmeter USES Faraday's law of electromagnetic induction to accurately measure the total flow rate throughout the process.
When conducting hydrodynamics flows in the tube, the working voltage E of the metal electrode is magnetically induced between a pair of metal electrodes placed in the direction of perpendicular bisecting the magnetic field.
The working voltage E of the metal electrode is proportional to the mean hydrodynamic rate V.
Characteristics of electromagnetic flowmeter
Applied emf diffuses (FF) produce a proper flow measurement, although the total flow is not symmetrical.
