Patent ID: 7475603

Claim:
A measurement transducer of vibration-type for a medium flowing in a pipeline, said measurement transducer comprising: a essentially straight measuring tube vibrating at least at times during operation and serving for conveying the medium, said measuring tube communicating with the pipeline via an inlet tube piece on an inlet end and an outlet tube piece on an outlet end; a counteroscillator affixed to the measuring tube at the inlet end to form a first coupling zone and at the outlet end to form a second coupling zone, said first and second coupling zones being imaginarily connected by a longitudinal axis of the measurement tube; a first cantilever for producing bending moments in the inlet tube piece, said first cantilever being coupled in the region of the first coupling zone essentially rigidly with the inlet tube piece and the measuring tube, said first cantilever having a first mass moment of inertia, J 15x , about an imaginary first rotational axis, D 15x , lying in the first coupling zone, as well as said first cantilever having a second mass moment of inertia, J 15z , about an imaginary second axis of rotation, D 15z , lying essentially parallel to the longitudinal axis of the measuring tube; and a second cantilever for producing bending moments in the outlet tube piece, said second cantilever being coupled in the region of the second coupling zone essentially rigidly with the outlet tube piece and the measuring tube, and said second cantilever having a first mass moment of inertia, J 16x , about an imaginary second axis of rotation, D 16x , lying in the second coupling zone and being essentially parallel to the first axis of rotation, D 15x , as well as said second cantilever having a second mass moment of inertia, J 16z , about an imaginary second axis of rotation, D 16z , lying essentially parallel to the longitudinal axis of the measuring tube, wherein a ratio, J 15x /J 15z , J 16x /J 16z , of the first mass moment of inertia, J 15x , J 16x , of each of the cantilevers to its respective second mass moment of inertia, J 15z , J 16z , is smaller than 5.
