Abstract:
1. A measuring transducer of vibration type for a medium flowing in a pipeline, comprising: a transducer housing; and an internal part arranged in said transducer housing, said internal part including at least a curved measuring tube serving for the conveying of the medium and vibrating, at least at times, during operation, and a counteroscillator affixed externally to said measuring tube forming a first coupling zone on an inlet-side of said measuring tube and a second coupling zone on an outlet-side of said measuring tube, wherein: said internal part is mounted oscillatably in said transducer housing, at least by means of two connecting tube pieces via which said measuring tube communicates during operation with the pipeline, and which are so oriented with respect to one another, as well as with respect to an imaginary longitudinal axis of the measuring transducer, that said internal part can move, during operation, with pendulum-like motion about said longitudinal axis; and said measuring tube and said counteroscillator are so embodied and so directed with respect to one another that both a center of mass of said measuring tube spaced from the imaginary longitudinal axis, as well as also a center of mass of said counteroscillator spaced from the imaginary longitudinal axis, lie in a common region of the measuring transducer spanned by the imaginary longitudinal axis and said measuring tube, and the center of mass of said measuring tube additionally is spaced farther from the longitudinal axis than the center of mass of said counteroscillator.
