Measuring apparatus for the detection of mass flow rate following the Coriolis principle

摘要

The invention relates to a measuring apparatus for the detection of mass flow rates using the Coriolis principle. In order to prevent detuning of the natural oscillations of the measurement tube that are used in order to determine the mass flow rate, which detuning is caused by feedback of oscillations which have been introduced into the clamping points of the measurement tube, it is provided according to the invention to connect to the measurement tube clamping device an antiresonator whose resonance spectrum has a prescribed bandwidth and is tuned to at least one natural oscillation of the measurement tube.
