Abstract
A 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. The measuring transducer comprises: a transducer housing; four, straight, measuring tubes connected to flow dividers for guiding flowing medium along flow paths. Each of the four measuring tubes opens with an inlet-side, measuring tube end into one the flow openings of an inlet-side, flow divider and with an outlet-side, measuring tube end into one of the flow openings. An electromechanical exciter mechanism for producing and/or maintaining mechanical oscillations of the four measuring tubes. The exciter mechanism is embodied in such a manner, that, 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.
