ABSTRACT:
The inductive flow meter and method of exciting a coil includes a coil with unipolar excitation, which generates exciting pulses having a pulse interval therebetween. The length of the pulse interval is shorter than that of an exciting pulse. The associated evaluation circuit includes two alternately clocked channels whose evaluation phases overlap each other in time, the measuring voltage being obtained at the ends of the signal paths by alternately sampling the channels.
