The measuring
system comprises: A measuring
transducer of vibration-type, through which medium flows during operation and which produces primary signals corresponding to parameters, especially a
mass flow rate, a density and / or a
viscosity, of the flowing medium; as well as a
transmitter electronics electrically coupled with the measuring
transducer for activating the measuring
transducer and for evaluating primary signals delivered by the measuring transducer. The measuring transducer includes at least one measuring tube for conveying flowing medium; at least one electro-mechanical, oscillation
exciter for exciting and / or maintaining vibrations of the at least one measuring tube, a first oscillation sensor for registering inlet-side vibrations at least of the at least one measuring tube and for producing a first primary
signal of the measuring transducer representing vibrations at least of the at least one measuring tube, and a second oscillation sensor for registering outlet-side vibrations at least of the at least one measuring tube and for producing a second primary
signal of the measuring transducer representing vibrations at least of the at least one measuring tube. The
transmitter electronics, in turn, delivers at least one driver
signal for the oscillation
exciter for effecting vibrations of the at least one measuring tube and generates, by means of the first primary signal and by means of the second primary signal, as well as with application of a Reynolds number, measured value representing a Reynolds number, Re, for medium flowing in the measuring transducer, a
pressure difference, measured value, which represents a
pressure difference occurring between two predetermined reference points in the flowing medium.
