Abstract:
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 antivibrator fixed to an inlet end and an outlet end of said flow tube; a transducer case fixed to said inlet-side tube section and said outlet-side tube section; 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 said inlet-side tube section, for causing bending moments which elastically deform said inlet-side tube section; and a second cantilever, fixed to an inlet end of said outlet-side tube section, for causing bending moments which elastically deform said outlet-side tube section, wherein: said first cantilever having a centroid being located in the area of said inlet-side tube section, and said second cantilever having a centroid being located in the area of said 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 said flow tube.
