Abstract
A measuring transducer comprises a measuring tube having an inlet-side tube end and an outlet-side tube end, a tube wall having a predetermined wall thickness and a lumen surrounded by the tube wall and extending between the first and second tube end, a support element, which with a support end is mechanically connected with the tube end and with a support end is mechanically connected with the tube end, as well as, laterally spaced from the measuring tube, a support element, which with a support end is mechanically coupled with the support end and with a support end is mechanically coupled with the support end. The measuring tube is adapted to guide a flowing medium in its lumen and caused to oscillate about a static resting position for producing Coriolis forces. An oscillation exciter as well as at least one oscillation sensor. The measuring transducer has a wanted mode having a resonant frequency, in which the measuring tube can execute wanted oscillations around its static resting position suitable for producing Coriolis forces and having a wanted frequency corresponding to the resonant frequency of the wanted mode. The oscillation exciter is placed externally on the measuring…
