The electromagnetic flow meters are ideally suited for flowmeasurement of all liquids with a minimum conductivity of 5 µS/cm. These meters are very accurate abd the flow measurement is independent of density, temperature and pressure of the medium.

Messuring principle
The operating principle of the electromagnetic flow meter is based on Faraday’s law of magnetic induction: The voltage induced across any conductor, as it moves at right angles through a magnetic field, is proportional to the velocity of that conductor. The voltage induced within the fluid is measured by two diametrically opposed internally mounted electrodes. The induced signal voltage is proportional to the product of the magnetic flux density, the distance between the electrodes and the average flow velocity of the fluid.
