ELECTROMAGNETIC FLOW METER
The working principle of a magnetic flow meter is based on Faraday’s law of electromagnetic induction.
According to Faraday’s law, when the conductive fluid flows through a magnetic field of the sensor, an electromotive force proportional to the volume flow is generated between the pair of electrodes, which is perpendicular to the flow direction and the magnetic field.
The amplitude of the electromotive force can be expressed as:
E = kBDv
Where E:Induced electric potential,
K: constant,
B:Magnetic flux density,
D:The inner diameter of the measuring Tube,
V:The average velocity of the fluid in the
axial direction of the electrode cross-section inside
the measuring tube.
