A mass flow meter operating by the Coriolis principle, with a measuring tube through which flows a medium, at least one exciter associated with and exciting the measuring tube, and at least one sensor associated with the measuring tube for capturing the Coriolis forces and/or the Coriolis-force-induced oscillations. The measuring tube is designed as a thin shell. A thin shell is understood to be characterized by a wall thickness h much smaller than its radius R, and a length L of the same order of magnitude of the radius R. The mass flow meter according to the invention uses vibration modes with more than one circumferential wave. Thus, a mass flow meter with high sensitivity and low pressure drop is achieved. |
