iSOLV EFS803B Battery Powered Electromagnetic Flowmeter
iSOLV electromagnetic flowmeter can be used for precise flow measurement of all electrically conductive liquids - sludges, slurries, sewage, milk, water. The only pre-requisite being that the minimum conductivity of the medium is greater than 5µS/cm. Temperature, viscosity, density has no influence on the measurement.

The measuring principle of the electromagnetic flowmeter (Magmeter) is based upon the Faraday’s Law of electromagnetic induction; whereby a voltage is induced by an electrical conductor passing through a magnetic field.
The following equation is applicable to the induced voltage:
U = kBVD
where :
U Induced voltage
k Instrument constant
B Magnetic field strength
V Velocity of the conductor
D Conductor width
In electromagnetic flowmeter, the medium acts as the electrical conductor when flowing through the meter tube, the induced voltage is proportional to the average flow velocity (the faster the flow rate, the higher the voltage). The induced voltage is picked up by a pair of electrodes (mounted in the meter tube) and transmitted to a flow transmitter to produce various standardized output signals.
Using the pipe cross-sectional area, the flow volume is calculated by the transmitter.
