Abstract

A measuring system comprises: a measuring transducer for producing oscillation measurement signals; and transmitter electronics electrically coupled with the measuring transducer for activating the measuring transducer and for evaluating oscillation measurement signals delivered by the measuring transducer. The measuring transducer includes: a transducer housing, a first housing end housing end, first flow divider having exactly four flow openings, an outlet-side, second housing end formed by means of an outlet-side, second flow divider having exactly four flow openings mutually spaced from one another, and a tube arrangement having exactly four, straight, measuring tubes forming flow paths arranged for parallel flow and connected to the flow dividers, an electromechanical exciter mechanism for producing and/or maintaining mechanical oscillations of the four measuring tubes and a vibration sensor arrangement reacting to vibrations of the measuring tubes.
