Abstract:
1. A measuring transducer of the vibration type for registering at least one physical, measured variable of a flowable medium conveyed in a pipeline and/or for producing Coriolis forces serving for registering a mass flow rate of a flowable medium conveyed in a pipeline, said measuring transducer comprising: a transducer housing, an inlet-side, first housing end of said transducer housing is formed by means of an inlet-side, first flow divider including four, mutually spaced flow openings, and an outlet-side, second housing end of said transducer housing is formed by means of an outlet-side, second flow divider including four, mutually spaced flow openings; a tube arrangement including four curved or bent measuring tubes, which are connected to said flow dividers for guiding flowing medium along flow paths connected in parallel, of which measuring tubes: 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 said first flow divider and with an outlet-side, second measuring tube end into a second flow opening of said second flow divider, a third measuring tube opens with an inlet-side, first measuring tube end into a third flow opening of said first flow divider and with an outlet-side, second measuring tube end into a third flow opening of said second flow divider, and a fourth measuring tube, opens with an inlet-side, first measuring tube end into a fourth flow opening of said first flow divider and with an outlet-side, second measuring tube end into a fourth flow opening of said second flow divider; a first coupling element of the first type, which is spaced both from said first flow divider as well as also from said second flow divider, and affixed, to each of the four measuring tubes and which serves for setting eigenfrequencies of natural oscillation modes of said tube arrangement, in which each of the four measuring tubes simultaneously executes or can execute bending oscillations about a respective static resting position; and an electro-mechanical exciter mechanism for producing and/or maintaining bending oscillations of each of said four measuring tubes, wherein: said two flow dividers are embodied and arranged in the measuring transducer in such a manner, that an imaginary first connecting axis of the measuring transducer imaginarily connecting said first flow opening of said first flow divider with the first flow opening of said second flow divider extends parallel to an imaginary second connecting axis of the measuring transducer imaginarily connecting the second flow opening of said first flow divider with the second flow opening of said second flow divider, and that an imaginary third connecting axis of the measuring transducer imaginarily connecting the third flow opening of said first flow divider with the third flow opening of said second flow divider extends parallel to an imaginary fourth connecting axis of the measuring transducer imaginarily connecting the fourth flow opening of said first flow divider with the fourth flow opening of said second flow divider; the measuring tubes are embodied and arranged in such a manner, that said tube arrangement exhibits a first imaginary longitudinal section plane extending both between the first measuring tube and the third measuring tube, as well as also between the second measuring tube and the fourth measuring tube, and that said tube arrangement exhibits a second imaginary longitudinal section plane perpendicular to its imaginary first longitudinal section plane and extending both between the first measuring tube and the second measuring tube as well as also between the third measuring tube and the fourth measuring tube; and said first coupling element of the first type includes a deformation body and four connecting struts, of which connecting struts: a first connecting strut is connected with said deformation body and with the first measuring tube, a second connecting strut is connected with said deformation body and with the second measuring tube, a third connecting strut is connected with said deformation body and with the first measuring tube, and a fourth connecting strut is connected with said deformation body and with the fourth measuring tube.
