Vibratory measuring device having a measuring tube

A vibratory measuring device for determining a mass flow rate or a density of a flowable medium, the device comprising:

• a vibratory measuring tube that is bent in the rest position thereof and configured to convey a medium therethrough, wherein the measuring tube has a measuring tube center line extending in a measuring tube plane;
• a first bearing body disposed at or near an inlet side of the measuring tube;
• a second bearing body disposed at or near an outlet side of the measuring tube;
• a support body, wherein the first bearing body and second bearing body are connected to the support body, wherein the measuring tube is supported on the first bearing body and second bearing body such that bending vibration modes of the measuring tube have vibration nodes at the first bearing body and second bearing body;
• a first exciter unit;
• a second exciter unit, wherein the first and second exciter units are each configured to excite bending vibrations of the measuring tube both in the measuring tube plane and perpendicular to the measuring tube plane as a function of excitation signals;
• a first sensor unit;
• a second sensor unit, wherein the first and second sensor units are each configured to detect bending vibrations of the measuring tube both in the measuring tube plane and perpendicular to the measuring tube plane and configured to generate vibration-dependent sensor signals;
• and
• an operation and evaluation circuit, wherein the operation and evaluation circuit is configured to supply excitation signals to the first and second exciter units as to selectively excite bending vibration modes and configured to receive the sensor signals of the sensor units.
