Electromagnetic flowmeters use Faraday’s Law to determine the flow of liquid in a pipe. Whereby, the flow of a conductive liquid through the magnetic field causes a voltage signal to be sensed by electrodes located on the flow tube walls. The voltage generated is proportional to the movement of the flowing liquid. In other words, the faster the fluid flows, the more voltage is generated. The electromagnetic flowmeter therefore processes the voltage signal to determine liquid flow.

Electromagnetic Flowmeter Principle

When an electrically conductive fluid flows in the pipe, an electrode voltage E is induced between a pair of electrodes placed at right angles to the direction of magnetic field.
The electrode voltage E is directly proportional to the average fluid velocity V.

Functional Magnetic Field Distribution (F.F) provides correct flow measurement in spite of uneven flow.

Manas’s original Noise-suppression circuit shuts off the slurry noise and achieves stable flow measurement with high accuracy.

Manas's original Noise-suppression circuit shuts off the noise induced by slurry or commercial frequency.
It always keeps stable flow measurement with high accuracy.
