Electromagnetic Flow Meter

Electromagnetic Flowmeters are based on Faraday\'s Law of Electromagnectic Induction.

In an Electromagnetic Flowmeter, the magnetic field is generated by a set of coils. As the conductive liquid passes through the electromagnetic field, an electric voltage is induced i the liquid which is directly proportial to its velocity. This induced voltage is perpendicular to both, the liquid flow direction and the electromagnetic field direction. The voltage sensed by the electrodes is further processed by the transmitter to give standardised output signal or displayed in appropriate engineering unit.

The flux density of the electromagnetic field in a given Flowmeter and the distance betwen the electrodes are constant. Therefore, the induced voltage is only a function of liquid velocity.



A rotameter is a device that measures the volumetric flow rate of fluid in a closed tube.

It belongs to a class of meters called variable area meters, which measure flow rate by allowing the cross-sectional area the fluid travels through to vary, causing a measurable effect.
