Abstract
The sensor includes at least one measuring tube for guiding a fluid The measuring tube an inlet end and an outlet end, and vibrating at least at times. The measuring tube communicates, by way of a first tube segment leading into the inlet end and a second tube segment leading into the outlet end, with a pipeline connected for allowing the fluid to flow through the measuring tube. The measuring tube is held oscillatably by means of a support, which is secured to the first tube segment by means of a first transition piece and to the second tube segment by means of a second transition piece. Especially for producing mass-flow-dependent, Coriolis forces and/or for producing viscosity-dependent frictional forces in flowing fluids, the measuring tube executes, during operation, mechanical oscillations about an oscillation axis (S) imaginarily connecting the two tube segments. For making the holding of the measuring tube twist-safe, at least one of the two transition pieces has a stop with a first stop-edge partially contacting the associated tube segment, respectively, and extending at least sectionally in the direction of the oscillation axis(S). By means of the stop, twisting of the su…
