摘要
A method for operating a Coriolis mass flowmeter having at least one controller, at least one electric actuating device, at least one electromagnetic driving mechanism with a drive coil as oscillation generator, at least one measuring tube and at least one oscillation sensor involves excited oscillation of the measuring tube being detected by the oscillation sensor and emitted as at least one output signal and the electric actuating device causing the electromagnetic driving mechanism to produce oscillation of the measuring tube largely in resonance by the output signal of the oscillation sensor, the drive voltage at the drive coil, and phasing of the drive current in relation to the phasing of the output signal of the oscillation sensor being determined and a new target phasing for the drive voltage derived from the determinations and supplied to the controller to generate a drive voltage with the new target phasing.
