Magnetic flow meter operation is based on Faraday’s law of electromagnetic induction.
“The voltage (E) induced in a conductor of length (D) moving through a magnetic field (H) is proportional to the velocity (V) of the conductor”
where C is the dimensional constant .
The magnetic flow meter measures volume rate at the flowing temperature independent of the effect of Viscosity , Density , Turbulence ,or suspended material
Most liquids can be measured by magnetic flow meters.
Electrical conductivity of liquid
Application of Magnetic flow meter Water , acids , base ,slurries ,liquids with suspended solids and industrial wastes are common applications .
