This is a magnetical method allowing to control the physico-chemical characteristics (hardness, nuance) or to detecte volume indications (leakage,...)

Its principal is to produce induction of a variable magnetic field in a conductor room. The induced magnetic field will create a-whirl flows in the room, known as Eddy's flows. Those currents will then generate a magnetic field, opposed to the initial one, and thus modify the impedance of the sensor.
