Abstract: In the method according to the invention, at least one oscillating measurement signal is produced as a primary signal of first class representing the vibrations of the measurement tube (MR) through which medium to be measured is currently flowing, and at least one oscillating measurement signal is produced as a primary signal of second class representing vibrations of at least one measurement tube (MR), through which no medium flows, surrounding the rotational axis (DA) of the carousel filling machine (RF), in particular the measurement transducer (MW) thereof. Moreover, at least one measurement value is generated representing a measurement parameter, in particular a mass flow rate and/or a totalized mass flow and/or a density of the medium to be measured, based on both the primary signal of first class as well as the primary signal of second class, and the invention further relates to a device suited for the implementation of the method and/or designed as a carousel filling machine (RF).

Abstract: The invention relates to a measuring system which comprises a vibration transducer through which, when operated, a medium flows, for producing vibration signals that depend on a viscosity of the flowing medium and/or on a Reynolds number of the flowing medium, and to an electronic transducer system which is electrically coupled to the transducer for controlling the transducer and for evaluating vibration signals supplied by the transducer. The transducer comprises a splitter (20
1 ) on the inlet side which has four interspaced flow openings (20
1A , 20
1B , 20
1C , 20
1D ), a splitter (20
2 ) on the outlet side which has four interspaced flow openings (20
2A , 20
2B , 20
2C , 20
2D ), four straight measuring tubes (18
1 , 18
2 , 18
3 , 18
4 ) for guiding the flowing medium which tubes are connected to the splitters (20
1 , 20
2 ) to give a system of tubes with fluidically parallel flow paths, and an electro-mechanical exciter arrangement (4) for exciting and maintaining mechanical vibrations of the measuring tubes (18
1 , 18
2 ). The measuring tube end on the inlet side of each of the four measuring tubes leads to a flow opening (20
1A ) of the splitter (20
1 ) on the inlet side and the second measuring tube on the outlet side leads to a flow opening (20
2A ) of the splitter (20
2 ) on the outlet end, a first measuring tube end on the inlet side of a third measuring tube (18
3 ) leads to a third flow opening (20
1C ) of the first splitter (20
1 ) and a second measuring tube end on the outlet side leads to a third flow opening (20
2C ) of the second splitter (20
2 ) and a first measuring tube end on the inlet side of a fourth measuring tube (18
4 ) leads to a fourth flow opening (20
1D ) of the first splitter (20
1 ) and a second measuring tube end on the outlet side leads to a fourth flow opening (20
2D ) of the second splitter (20
2 ). The electronic transducer system feeds electrical excitation power to the exciter arrangement by means of an electrical driver signal supplied to the exciter arrangement, while the exciter arrangement converts electrical excitation power, at least proportionally, to torsional vibrations of the first measuring tube (18
1 ) and to torsional vibrations of the second measuring tube (18
2 ) which are diametrically opposed to the torsional vibrations of the first measuring tube (18
1 ), and to torsional vibrations of the third measuring tube (18
3 ) and to torsional vibrations of the fourth measuring tube (18
4 ) which are diametrically opposed to the torsional vibrations of the third measuring tube (18
3 ).
