The measuring transducer serves for registering at least one physical, measured variable of a flowable medium guided in a pipeline and/or for producing Coriolis forces serving for registering a mass flow rate of a flowable medium guided in a pipeline. For such purpose, 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 exactly four flow openings (201A, 201B, 201C, 201D) spaced, in each case, from one another and an outlet-side, housing end is formed by means of an outlet-side, flow divider (202) having exactly four flow openings (202A, 202B, 202C, 202D) spaced, in each case, from one another; as well as exactly four, straight, measuring tubes (181, 182, 183, 184) connected to the flow dividers (201, 202) for guiding flowing medium along flow paths connected in parallel. Each of the four measuring tubes opens with an inlet-side, measuring tube end into one the flow openings (201A, 201B, 201C, 201D) of the inlet-side, flow divider (201) and with an outlet-side, measuring tube end into one the flow openings (202A, 202B, 202C, 202D) of the outlet-side, flow divider (202). Additionally, the measuring transducer includes an electromechanical exciter mechanism (5) for producing and/or maintaining mechanical oscillations of the four measuring tubes (181, 182, 183, 184), 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 (XZ1, XZ2). The measuring transducer of the invention 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.
