摘要

PROBLEM TO BE SOLVED: To provide a method for controlling an oscillator acting to a Coriolis conduit of a Coriolis flow rate measuring apparatus for fluid, and a power feed circuit for oscillator which can utilize an existing electric energy well for feeding power to an oscillator with the use of the single or a plurality of the oscillators. ;SOLUTION: In the method for controlling an oscillator acting to a Coriolis conduit of a Coriolis flow rate measuring apparatus for fluid, and the power feed device for the oscillator of the fluid flow rate measuring apparatus based on the Coriolis principle, pulse-shaped sine wave signals modulated in pulse width are supplied to the oscillator. Since a heat loss at an amplifier circuit is reduced, an electric power utilizable to feed power to the oscillator can be used more favorably.;COPYRIGHT: (C)2001,JPO
