Abstract:
A mass flow meter for flowing media, which operates according to the Coriolis principle, with one at least essentially straight Coriolis measuring tube having a thick wall with an outside and an inside surface defining a flow channel with at least one vibration converter acting on the Coriolis measuring tube, so that a pressure wave is propagated through the wall of the tube, said pressure wave having a wavelength, and with at least one sensor detecting at least one of Coriolis forces and Coriolis oscillations based on Coriolis forces, wherein said vibration converter is on the outside of the Coriolis measuring tube and the vibration frequency generated by the vibration converter is such that the thickness of said tube wall is an integral multiple of half the wavelength of the pressure wave propagating through the tube wall whereby a maximum deflection of said inner surface takes place.
