Claim Text:
1. A measuring transducer of vibration-type for registering at least one physical, measured variable of a flowable medium guided in a pipeline and/or for producing Coriolis forces serving for registering a mass flow rate of a flowable medium guided in a pipeline, said measuring transducer comprising: a transducer housing with an inlet-side, first housing end formed by means of an inlet-side, first flow divider including four, mutually spaced, flow openings and with an outlet-side, second housing end formed by means of an outlet-side, second flow divider including exactly four, mutually spaced, flow openings; a tube arrangement including four, curved, or bent measuring tubes, which are connected to the flow dividers for guiding flowing medium along flow paths connected in parallel, of which: a first measuring tube opens with an inlet-side, first measuring tube end into a first flow opening of the first flow divider and with an outlet-side, second measuring tube end into a first flow opening of the second flow divider, a second measuring tube opens with an inlet-side, first measuring tube end into a second flow opening of the first flow divider and with an outlet-side, second measuring tube end into a second flow opening of the second flow divider, a third measuring tube opens with an inlet-side, first measuring tube end into a third flow opening of the first flow divider and with an outlet-side, second measuring tube end into a third flow opening of the second flow divider and a fourth measuring tube opens with an inlet-side, first measuring tube end into a fourth flow opening of the first flow divider and with an outlet-side, second measuring tube end into a fourth flow opening of the second flow divider; and an electro-mechanical exciter mechanism for producing and/or maintaining bending oscillations each of the four measuring tubes, the two flow dividers being embodied and arranged in the measuring transducer, that an imaginary first connecting axis of the measuring transducer imaginarily connecting the first flow opening of the first flow divider with the first flow opening of the second flow divider extends parallel to an imaginary second connecting axis of the measuring transducer imaginarily connecting the second flow opening of the first flow divider with the second flow opening of the second flow divider, and that an imaginary third connecting axis of the measuring transducer imaginarily connecting the third flow opening of the first flow divider with the third flow opening of the second flow divider extends parallel to an imaginary fourth connecting axis of the measuring transducer imaginarily connecting the fourth flow opening of the first flow divider with the fourth flow opening of the second flow divider; the measuring tubes being embodied and arranged in the measuring transducer, that the tube arrangement exhibits lying both between the first measuring tube and the third measuring tube and between the second measuring tube and the fourth measuring tube a first imaginary longitudinal-section plane, and that the tube arrangement exhibits perpendicular to its imaginary first longitudinal-section plane and extending both between the first measuring tube and second measuring tube and between the third measuring tube and fourth measuring tube a second imaginary longitudinal-section plane, and that the tube arrangement exhibits a natural bending oscillation mode of first type, in which mode: the first measuring tube and the second measuring tube execute, relative to the second imaginary longitudinal section plane, opposite equal bending oscillations about, in each case, a static rest position associated with the respective measuring tube; and the third measuring tube and the fourth measuring tube execute, relative to the second imaginary longitudinal section plane, opposite equal bending oscillations about, in each case, a static rest position associated with the respective measuring tube, wherein: in said natural bending oscillation mode of first type, said bending oscillations of the first measuring tube are also opposite equal to said bending oscillations of the third measuring tube, relative to the second imaginary longitudinal section plane; and said bending oscillations of the second measuring tube are also opposite equal to said bending oscillations of the fourth measuring tube, relative to the second imaginary longitudinal section plane; and the exciter mechanism is adapted to excite the bending oscillation mode of first type.
