摘要： A vibratory transducer comprises a flow tube for conducting the fluid flowing in a pipe. The flow tube communicates with the pipe via an inlet-side tube section and an outlet-side tube section. An antivibrator is mechanically connected with the flow tube by an inlet-side coupler and an outlet-side coupler. For driving flow tube and antivibrator at an excitation frequency the transducer comprising an excitation system and for sensing inlet-side and outlet-side vibrations of the flow tube the transducer comprising a sensor system. An internal system formed by the flow tube, the antivibrator, the excitation system, and the sensor system, oscillating about a longitudinal axis of the transducer which is essentially in alignment with the inlet-side tube sections, forces a torsion of the couplers about the longitudinal axis and an essentially torsional elastic deformation of the inlet-side and outlet-side tube sections. The couplers are so dimensioned that an inherent torsion eigenmode of the inlet-side coupler and the inlet-side tube section has a natural frequency approximately equal to the excitation frequency, and an inherent torsion eigenmode of the outlet-side coupler and outlet-side tube section has a natural frequency essentially equal to the natural frequency of the inlet-side inherent torsion eigenmode.
