    摘要： 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 ).

    摘要： The invention relates to a measuring transducer comprising a housing and an inner part arranged in the housing. The inner part comprises at least one curved measuring tube (10) which vibrates at least intermittently during operation and is used to guide the medium, and a counter-oscillator (20) which is fixed to the measuring tube (10) on the inlet side in such a way as to form a coupling region (11#), and on the outlet side in such a way as to form a coupling region (12#). The inner part is held in a vibrating manner in the converter housing at least by means of two connection tubular pieces (11, 12) which enable the measuring tube (10) to communicate with the tubular line during operation, and which are oriented in relation to each other and to an imaginary longitudinal axis (L) of the measuring transducer, such that the inner part can oscillate about the longitudinal axis (L) during operation. Furthermore, the measuring tube (10) and counter-oscillator (20) are embodied and oriented in relation to each other in such a way that both a centre of mass M10 of the measuring tube, located at a certain distance from the imaginary longitudinal axis (L), and a centre of mass M20 of the counter-oscillator (20), located at a certain distance from the imaginary longitudinal axis, lie in a common region of the measuring transducer which is defined by the imaginary longitudinal axis (L) and the measuring tube (10), and in such a way that the centre of mass M10 of the measuring tube (10) is located further away from the longitudinal axis (L) than the centre of mass M20 of the counter-oscillator (20).

    摘要： The invention relates to a measuring sensor comprising a sensor housing (10) with a plurality of natural vibratory modes, and at least one first sensor tube (4) which is held in the sensor housing (10) in such a way that it vibrates intermittently, and is used to guide at least one partial volume of the medium to be measured. Said measuring sensor also comprises an electromechanical, especially electrodynamic, exciter arrangement (60) for generating and/or maintaining mechanical vibrations of the sensor tube (4), and a sensor arrangement which reacts to movements of the sensor tube (4), especially bending vibrations, and is used to generate at least one vibratory measuring signal (SVb) representing vibrations of the sensor tube (4). In order to improve the vibratory characteristics and thus the measuring precision of the measuring sensor, at least three coupling elements (217) connecting the first and the second sensor tubes (4,5) on the inlet side, and at least three coupling elements (218) connecting the first and second sensor tubes (4,5) on the outlet side are provided. The use of at least six coupling elements enables vibratory measuring sensors with high measuring precision to be produced, even for wide nominal widths of more than 150 mm, especially while largely maintaining already established and proven structural forms.
