A Coriolis flowmeter having an improved measurement accuracy, especially
in measurement applications, where conventional Coriolis flowmeters may
have a reduced accuracy due to erroneous flow spiking or outputs during
no-flow situations is described, comprising: a measurement tube, a driver
for imparting a force proportional to an applied excitation signal to the
measurement tube for setting the measurement tube into an oscillatory
motion, motion sensors for measuring the motion of the measurement tube,
an excitation signal generator, for generating the excitation signal to
be supplied to the driver based on the measurement signals derived by the
motion sensors, means for monitoring the excitation signal or a
damping-coefficient of a damping of the measurement tube and for
determining whether an amplitude (A) of the excitation signal or the
damping coefficient exceeds an application-specific range, and means for
determining a corrected flow (F.sub.c) of a fluid through the measurement
tube, wherein the corrected flow (F.sub.c) is determined based on
measurement signals derived by the motion sensors, when the excitation
signal or the damping coefficient has an amplitude, that lies within the
application-specific range and wherein the corrected flow (F.sub.c) is
set to an application-specific flow, when the excitation signal or the
damping coefficient has an amplitude, that exceeds the
application-specific range.
