Abstract

A process for activating an oscillator serving to oscillate a Coriolis line of a Coriolis mass flowmeter for moving fluids, and of a power supply circuit system for an oscillator of a mass flowmeter for moving fluids operating by the Coriolis principle. The oscillator is supplied a pulse-width-modulated pulsed sinusoidal signal. The resulting heat-loss reduction in an amplifier circuit leads to a better utilization of the energy available for supplying the oscillator.
