Patent ID: 7010989

Claim:
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 the transducer; a supporting frame fixed to an inlet end and an outlet end of the flow tube, said supporting frame providing an antivibrator which vibrates out of phase with said flow tube, an excitation system for driving the flow tube; a sensor system for sensing vibrations of the flow tube; a first cantilever, fixed to the inlet-side tube section, for causing bending moments which elastically deform the inlet-side tube section; and a second cantilever, fixed to 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 said inlet-side tube section and in the deforming said outlet-side tube section impulses are produced which are directed opposite to the transverse impulses produced in the vibrating flow tube.
