Abstract
A measuring transducer comprises: a transducer housing, an inlet-side, flow divider having exactly four spaced flow openings and an outlet-side, housing end by means of an outlet-side, flow divider having exactly four spaced flow openings; as well as exactly four, straight, measuring tubes connected to the flow dividers. Each of the four measuring tubes opens with an inlet-side, measuring tube end into one the flow openings and with an outlet-side, measuring tube end into one the flow openings of the outlet-side, flow divider. Additionally, the measuring transducer includes an electromechanical exciter mechanism, wherein the exciter mechanism is embodied in such a manner, that, therewith, the measuring tubes are excitable pairwise to execute opposite phase bending oscillations in, in each case, a shared imaginary plane of oscillation. The measuring transducer is suitable, especially, for measuring a density and/or a mass flow rate of a medium flowing in a pipeline, at least at times, with a mass flow rate of more than 2200 t/h.
