About Ultrasonic Level Meter Display Unit
Electromagnetic Flow Meters are based on FARADAYS LAW INDUCTION. These meters are also called as
Magflow or Electromagnetic Flow Meters. A magnetic field is applied to the metering tube, which results in a potential
difference proportional to the flow velocity perpendicular to the flux lines.
The physical principle at work is Electromagnetic Induction and mathematically defined as E=k*B*D*V.
where, E = Induced Voltage (Linear with velocity)
K = Proportionality Constant
B = Magnetic Field Strength (Coil Inductance)
D = Distance between electrodes
V = Velocity of process fluids
of a sensor and a converter that may be mounted integral to the sensor or remotely either with a field mount kit.
