Abstract:
1. A vibratory transducer for a fluid flowing in a pipe, said transducer comprising: a flow tube vibrating in operation, for conducting the fluid, said flow tube communicating with the pipe via an inlet-side tube section and an outlet side tube section, and said vibrating flow tube being, at least temporarily, laterally displaced from an assigned static rest position as a result of transverse impulses occurring in said vibratory transducer; an excitation system for driving said flow tube; a sensor system for sensing vibrations of said flow tube; a first cantilever, fixed to an outlet end of the inlet-side tube section, for causing bending moments which elastically deform the inlet-side tube section; and a second cantilever, fixed to an inlet end of the outlet-side tube section, for causing bending moments which elastically deform the outlet-side tube section, said first cantilever having a centroid being located in the area of the inlet-side tube section and said second cantilever having a centroid being located in the area of the outlet-side tube section, and said bending moments being such that in the deforming inlet-side tube section and in the deforming outlet-side tube section impulses are produced which are directed opposite to the transverse impulses produced in the vibrating flow tube.
