Patent ID: 7080564

Claim:
A vibratory transducer for a fluid flowing in a pipe, comprising: an essentially straight flow tube communicating with the pipe for conducting the fluid, said flow tube being operable to vibrate; an antivibrator fixed to said flow tube, said antivibrator extending essentially parallel to said flow tube; an excitation assembly acting on said flow tube for vibrating said flow tube; and a sensor arrangement for sensing vibrations of said flow tube, said sensor arrangement being adapted to sense both torsional vibration and flexural vibrations of said flow tube wherein: said sensor arrangement includes a sensor coil fixed to said antivibrator and an armature fixed to said flow tube; and said sensor coil is magnetically coupled to said armature such that a variable measurement voltage influenced by rotational and lateral relative motions between said flow tube and said antivibrator is induced in said sensor coil.
