A flow meter comprises electrodes (16, 18), induction windings (12, 14), a winding driver circuit (20), and a processor circuit (22). The winding excitation current is a combination of a current of period T.sub.1 and a current of period T.sub.2, where T.sub.2 >T.sub.1. The processor circuit (22) processes...http://www.google.fr/patents/US4709583?utm_source=gb-gplus-shareBrevet US4709583 - Electromagnetic flow meter using a pulsed magnetic field
