MAGNETOFLOW™ M1000 - Electromagnetic Flowmeter

Inductive electromagnetic flowmeters are best suitable for flow measurements of fluids with electrical conductivity from 5 μS/cm (20 μS/cm for demineralized water). This flowmeters range offers high accuracy. Results measurement are independant of density, temperature and pressure.

Detailinformationen

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.
Fuji Electric offers 2 electromagnetic measurement solutions for all your liquids flow management : MAGFLO flowmeters and MAGNETOFLOW flowmeters
