Electromagnetic flow meters are based on Faraday's law regarding magnetic induction: it establishes that a conductor (which is the liquid itself) immersed in a magnetic field produces at its extremes an electromotive force proportional to the speed with which the conductor cuts the lines of magnetic field flux.
Ideal for fluids: water, waste water, leachate, food liquids, wine, beer, chocolate, liquids with suspended solids, abrasive liquids, dirty liquids, glycerine, molasses, water-based paints, conductive acids.
Electromagnetic flowmeters are particularly suitable when you want to have a precise and accurate measurement. Being the electromagnetic meter an empty tube is suitable for dirty liquids and with suspended solids, or for food liquids.
The necessary conditions for the correct operation of the electromagnetic flow meter are: full tube and electrically conductive liquid.
