Abstract:
1. A vibratory transducer for a fluid flowing in a pipe, the transducer comprising: an essentially straight flow tube communicating with the pipe for conducting the fluid, said flow tube being connected to the pipe via an inlet tube section and via an outlet tube section, and said flow tube being operable to vibrate; an antivibrator fixed to said flow tube, said antivibrator extending essentially parallel to said flow tube and said antivibrator being connected to said flow tube to be essentially coaxial with said flow tube; an excitation assembly acting on said flow tube for vibrating said flow tube, said excitation assembly being adapted to excite said flow tube into torsional vibrations about its longitudinal axis, and to excite said flow tube into flexural vibrations; and a sensor arrangement for sensing vibrations of said flow tube.
