Abstract:
1. A vibration-type measuring transducer, comprising: at least one measuring tube for conveying a flowing medium, said at least one measuring tube extending with an oscillatory length between an inlet-side, first measuring tube end, and an outlet-side, second measuring tube end, and, said at least one measuring tube being at least sectionally curved and adapted to, oscillate about an oscillation axis, which is parallel to or coincides with an imagined connecting axis, which imaginarily connects said two measuring tubes ends; a sensor arrangement for registering oscillations at least of the at least one measuring tube, said sensor arrangement including a first oscillation sensor, which is arranged on said at least one measuring tube and which is adapted to deliver a first primary signal of the measuring transducer representing vibrations of said at least one measuring tube; and said sensor arrangement including a second oscillation sensor which is arranged on said at least one measuring tube spaced from said first measuring sensor and which is adapted to deliver a second primary signal of the measuring transducer representing vibrations of said at least one measuring tube, wherein: said at least one measuring tube includes an inlet-side, first straight tube segment, with an imaginary longitudinal axis exhibiting a direction vector pointing toward a first coupling zone, and an outlet-side, second straight tube segment, with an imaginary longitudinal axis exhibiting a direction vector pointing toward a second coupling zone, said first and said second straight segments of tube are arranged with respect to one another in such a way that said direction vector of the first straight tube segment and that said direction vector of the second straight tube segment intersect to form an angle, Θ, in such a way that said angle, Θ, exhibits a size of less than 170° and greater than 10°, and said first oscillation sensor of said sensor arrangement and said second oscillation sensor of said sensor arrangement are placed in the measuring transducer in such a way, that a measuring length of the measuring transducer corresponding to a length of a region extending between said first oscillation sensor and said second oscillation sensor corresponds to less than 65%, of the oscillatory length, and greater than 25%, of the oscillatory length.
