Patent ID: 7533580

Claim:
A Coriolis flowmeter comprising: a measurement tube; a driver for imparting a force proportional to an applied excitation signal to said measurement tube for setting said measurement tube into an oscillatory motion; motion sensors for measuring the motion of said measurement tube; an excitation signal generator, for generating the excitation signal to be supplied to said driver based on the measurement signals derived by said motion sensors, means for monitoring the excitation signal and for determining whether an amplitude of the excitation signal exceeds an application-specific range; and means for determining a corrected flow of a fluid through said measurement tube, wherein: the corrected flow is determined based on measurement signals derived by said motion sensors, when the excitation signal has an amplitude that lies within the application-specific range; and the corrected flow is set to an application-specific flow, when the excitation signal has an amplitude, that exceeds the application-specific range.
