摘要： A vibratory transducer comprises a flow tube for conducting the fluid flowing in a pipe. The flow tube communicates with the pipe via an inlet-side tube section and an outlet-side tube section. An antivibrator is mechanically connected with the flow tube by an inlet-side coupler and an outlet-side coupler. For driving flow tube and antivibrator at an excitation frequency the transducer comprising an excitation system and for sensing inlet-side and outlet-side vibrations of the flow tube the transducer comprising a sensor system. An internal system formed by the flow tube, the antivibrator, the excitation system, and the sensor system, oscillating about a longitudinal axis of the transducer which is essentially in alignment with the inlet-side tube sections, forces a torsion of the couplers about the longitudinal axis and an essentially torsional elastic deformation of the inlet-side and outlet-side tube sections. The couplers are so dimensioned that an inherent torsion eigenmode of the inlet-side coupler and the inlet-side tube section has a natural frequency approximately equal to the excitation frequency, and an inherent torsion eigenmode of the outlet-side coupler and outlet-side tube section has a natural frequency essentially equal to the natural frequency of the inlet-side inherent torsion eigenmode.

摘要： A single V-shaped tube (1) is bent in a plane and has an inlet section (11), an outlet section (12), an inlet bend (13), an outlet bend (14); a vertex bend (15) and a respective tube section (16, 17) between the inlet bend and the outlet bend. The distance between the vertex of the vertex bend and the inlet/outlet axis can be great. Two clamping bodies (2, 3) are clamped onto the tube sections defining a tube section. Flat bodies (31, 32) are fixed onto the clamping bodies (2, 3). Fixed to the flat bodies is an opposed-action body (41) which extends along the axis of symmetry (I—I) up to the vertex bend, where it supports a first portion of an exciter assembly (50) or a seismic exciter (50′) which excites the tube section in a third mode of vibration at an associated natural frequency f3. A sensor support (61) and a sensor support (62) are fixed to the flat body (31). A velocity or displacement sensor (71, 72) is fixed to the tube section and the sensor supports. Inlet section and outlet section are held by a supporting frame (35) to which a housing (8) is fixed.

摘要： The measuring system of the invention comprises: A measuring transducer of 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 a Reynolds number of the flowing medium; as well as a transmitter electronics electrically coupled with the measuring transducer for driven the measuring transducer and for evaluating oscillatory signals delivered by the measuring transducer. The measuring transducer includes: An inlet-side flow divider (201) having at least two, mutually spaced, flow openings (201A, 201B); an outlet-side flow divider (202) having at least two, mutually spaced, flow openings (202A, 202B); at least two, mutually parallel, straight, measuring tubes (181, 182) for conveying flowing medium, connected to the flow dividers (201, 202) for forming a tube arrangement having at least two flow paths for parallel flow; as well as an electromechanical exciter mechanism (4) for exciting and maintaining mechanical oscillations of the at least two measuring tubes (181, 182). Each of the at least two measuring tubes opens with an inlet-side measuring tube end into a flow opening (201A) of the inlet-side flow divider (201) and with an outlet-side, second measuring tube end into a flow opening (202A) of the outlet-side flow divider (202). The transmitter electronics feeds, by means of an electrical driver signal supplied to the exciter mechanism, electrical excitation power into the exciter mechanism, while the exciter mechanism converts electrical excitation power at least partially into opposite-equal torsional oscillations of the at least two measuring tubes (181, 182).
