Today's electromagnetic flowmeters operate on the Faraday principle: if a conductive liquid, moving at speed V inside a tube (whose diameter D is electrically insulated), passes perpendicularly through a magnetic field B, a voltage U is induced in the liquid. This voltage is picked up by two electrodes, which measure :
The converter collects the voltage at the electrodes...
