Abstract
A vibratory measuring device for determining a mass flow rate or a density of a medium includes: a vibratory measuring tube which is curved when in a rest position; a support body; a first bearing body; a second bearing body; two exciter units and two sensor units; and a circuit. The bearing bodies are connected to the support body such that flexural vibration modes of the measuring tube have vibration nodes on the bearing bodies, wherein the exciter units are configured to excite flexural vibrations of the measuring tube, wherein the sensor units are each configured to detect flexural vibrations of the measuring tube both in and perpendicular to the plane and to output vibration-dependent sensor signals, wherein the circuit is configured to output excitation signals to the excitation units for the selective excitation of flexural vibration modes and to receive the sensor signals of the sensor units.
