Electromagnetic flow metering is one of the oldest & most widely used across the industries. Magnetic flow meters are reliable & cost effective water flow measurement technology available.

We are proud to be associated with Shenitech, LLC to bring this flow measurement technology for water flow measurement application. These flow meters work on Faraday’s Law principle which depends on the conductivity of media. Our magnetic flow meters are used for domestic as well as industrial water flow application having high TDS, in Sewerage treatment & effluent treatment application.

Faraday’s Law principle is annotated as below.

“When a charged media moves in a direction which is perpendicular to the direction of magnetic field an electromagnetic flux is generated which is perpendicular to the direction of both motion of charged media & magnetic field & directly proportional to the mean velocity of charge particle & magnetic field.”

Suppose ‘D’ is the diameter of flow cell of the flow meter, ‘B’ is the magnetic field produced by the magnetically coupled coil, mounted on the side of meters inside coil housing & flow media moving unidirectional with velocity ‘v’ , then EMF generated ‘E’ is related to velocity as

E = BDv      Or      v = E/ (BD)

Cross section area of pipe is ‘A’
Then Flow rate ‘Q’ can be calculated as

Q = Ax E/ (BD)
