Abstract

A measuring transducer of vibration type for registering, on the basis of the Coriolis principle, at least one measured variable of a medium flowing through a pipeline. The measuring transducer includes: a measuring tube, which is connectable with the pipeline via an inlet and an outlet, wherein the measuring tube includes a first measuring tube arc and a second measuring tube arc; an oscillation exciter for exciting oscillations of the measuring tube arcs; at least one oscillation sensor for registering resulting oscillations of the measuring tube arcs; and a transducer housing surrounding the measuring tube arcs. The measuring tube arcs are elastically coupled to the transducer housing. In this way, a robust and reliable measuring operation is guaranteed, which is little influenced by oscillatory in-couplings.
