Patent ID: 8316722

Claim:
A measuring system for a medium flowing in a pipeline, said measuring system comprising: a measuring transducer of the vibration-type, through which medium flows during operation and which serves for producing oscillatory signals dependent on a viscosity of the flowing medium and/or dependent on a Reynolds number of the flowing medium; and transmitter electronics electrically coupled with said measuring transducer for driving said measuring transducer and for evaluating oscillatory signals delivered by said measuring transducer, wherein: said measuring transducer includes a transducer-housing of which an inlet-side, first housing end is formed by means of an inlet-side first flow divider with at least two, mutually spaced flow openings, and an outlet-side, second housing end by means of an outlet-side second flow divider with at least two, mutually spaced flow openings; for conveying flowing medium said measuring transducer including at least two mutually parallel straight measuring tubes, connected to said first and said second flow dividers, for forming a tube arrangement including at least two flow paths connected for parallel flow, of which measuring tubes; a first measuring tube opens with an inlet-side, first measuring tube end into a first flow opening of said first flow divider and with an outlet-side, second measuring tube end into a first flow opening of said second flow divider; and a second measuring tube opens with an inlet-side, first measuring tube end opening into a second flow opening of said first flow divider and with an outlet-side, second measuring tube end into a second flow opening of said second flow divider; said measuring transducer further including an electromechanical exciter mechanism for exciting and maintaining mechanical oscillations of said at least two measuring tubes; said transmitter electronics is adapted to feed electrical excitation power into said exciter mechanism by means of a variable and/or, at least at times, periodic, first electrical driver signal supplied to said exciter mechanism; and said exciter mechanism is adapted to convert the electrical excitation power at least partially, both into torsional oscillations of said first measuring tube and into torsional oscillations of said second measuring tube opposite-equal to the torsional oscillations of said first measuring tube.
