Abstract
The measuring transducer comprises: a transducer housing (71), of which an inlet-side, housing end is formed by means of an inlet-side, flow divider (201) having four flow openings (201A, 201B, 201C, 201D) and an outlet-side, housing end is formed by means of an outlet-side, flow divider (202) having four flow openings (202A, 202B, 202C, 202D); as well as a tube arrangement having four, curved, or bent, measuring tubes (181, 182, 183, 184) connected to the flow dividers (201, 202) for guiding flowing medium along flow paths connected in parallel, wherein each of the four measuring tubes opens with an inlet-side, measuring tube end into one of the flow openings of the flow divider (201) and with an outlet-side, measuring tube end into one the flow openings of the flow divider (202). The transducer further comprises an exciter mechanism for exciting oscillations of said measuring tube. The tube arrangement exhibits a natural bending oscillation mode, called V-Mode, and the exciter mechanism is adapted to excite bending oscillation in said V-mode.
