Abstract:
A measuring transducer, comprises at least one measuring tube for conveying a flowing medium. The measuring tube vibrates at least at times during operation. The measuring transducer further comprises a sensor arrangement, which serves to register oscillations of the measuring tube. The measuring tube extends with an oscillatory length between an inlet-side, first measuring tube end and an outlet-side, second measuring tube end, and, during operation, oscillates about an oscillation axis, which is parallel to or coincides with an imagined connecting axis which imaginarily connects the two measuring tube ends. By means of a first oscillation sensor, which is arranged on the measuring tube, the sensor arrangement produces a first primary signal representing vibrations of the measuring tube, and by means of a second oscillation sensor, which is arranged on the measuring tube spaced from the first measuring sensor, the sensor arrangement produces a second primary signal representing vibrations of the measuring tube. The oscillation sensors of the sensor arrangement are placed in the measuring transducer in such a way that a measuring length of the measuring transducer corresponds to less than 65% especially less than 55% of the oscillatory length, and greater than 25%, especially greater than 30% of the oscillatory length.
