A mass flow meter for flowing media, which operates according to the Coriolis principle, has a straight Coriolis measuring tube, an oscillation generator acting on the Coriolis measuring tube, and at least one sensor detecting Coriolis forces and/or Coriolis oscillations based on Coriolis forces. The problem which results from the fact the mass flow meter has only one straight Coriolis measuring tube is largely eliminated by designing the Coriolis measuring tube as a flow channel of a thick-walled body, namely a thick-walled tube, the thick-walled tube having recesses accessible from the outside and reaching very close to the Coriolis measuring tube. The oscillation generator acts upon the residual material of the thick-walled tube remaining in the area of the recesses, and the Coriolis forces or Coriolis oscillations appearing in the area of the residual material of the thick-walled tube are detected by each sensor.

[ What is claimed is:] [1.] A mass flow meter for flowing media, which operates according to the Coriolis principle, with one at least essentially straight Coriolis measuring tube, with at least one oscillation generator acting on the Coriolis measuring tube, and with at least one sensor detecting at least one of Coriolis forces and Coriolis oscillations based on Coriolis forces, wherein the Coriolis measuring tube has a thick wall (4) defining a flow channel (1), the thick wall (4) has recesses (5) accessible from the outside and reaching very close to the flow channel (1) so as to have residual material (6) between the recesses (5) and the flow channel (1), the oscillation generator (2) acts upon the residual material (6), and the Coriolis forces or Coriolis oscillations appearing in the area of the residual material (6) are detected by said at least one sensor (3).
