Patent ID: 7690269

Claim:
A mass flow meter, comprising: a measuring tube; a vibration generator, wherein the vibration generator is essentially arranged in an axial center of the measuring tube to energize the measuring tube to oscillate in a first bending mode; a measurement value sensor to detect Coriolis forces; a chamber, wherein the measuring tube is mounted in the chamber, and wherein the chamber has a first opening and a second opening to direct a medium to and from respective ends of the measuring tube; and a first bearing and a second bearing for mounting the measuring tube, wherein the first and second bearings are located essentially in the region of oscillation nodes at an axial distance from the two tube ends respectively, wherein a first end of the measuring tube is arranged opposite the first opening such that a first free gap remains between the first end and the chamber, and wherein a second end of the measuring tube is arranged opposite the second opening such that a second free gap remains between the second end and the chamber.
