摘要： This mass flow/density sensor (10), which can be installed in a pipe and through which a fluid to be measured flows during operation, is to be balanced over a wide density range, so that accurate measurements are possible. A single straight measuring tube (13) having a longitudinal axis (131) extends between its inlet end (11) and the outlet end (12) and is fixed to a support, e.g., a cylindrical tube (14, 14'). The support has a longitudinal centroidal line (141) which is parallel to, but does not coincide with, the longitudinal axis (131) of the measuring tube. A cantilever (15) is fixed to the measuring tube (13) midway between the inlet and outlet ends (11, 12) and in operation causes the measuring tube to vibrate either in a first fundamental flexural mode or in a second fundamental flexural mode having a higher frequency than this first mode. An excitation arrangement (16) disposed midway between the end pieces excites the measuring tube (13) in the second mode. Sensors (17, 18) for the motions of the measuring tube on the inlet and outlet side are positioned between the middle of the tube and the inlet and outlet ends, respectively. The support may be provided with a counterbalance. Because of the torsional vibrations exerted by the cantilever on the measuring tube, the sensor is also well suited for measuring the viscosity of the fluid.

摘要： A Coriolis mass flow/density sensor which can be installed in a pipe and through which a fluid to be measured flows during operation is balanced over a wide density range so that accurate measurements are possible. The Coriolis mass flow/density sensor includes a measuring tube, an excitation arrangement for exciting the measuring tube to vibrate in a second fundamental flexural mode of vibration; and a counterbalance member attached to the measuring tube which counterbalances the vibration of the measuring tube. A cantilever can be attached to the measuring tube midway between the inlet end and the outlet end of the measuring tube. First and second sensors sense the measuring tube vibration on the inlet and outlet sides of the measuring tube, respectively.

摘要： The Coriolis mass-flow/density meter includes at least one measuring tube (11), which is traversed in operation by the medium. A support means (12) of the Coriolis mass-flow/density meter is fixed at an inlet end and at an outlet end of the measuring tube 11 and thus clamps the measuring tube such that it can oscillate. In operation, the measuring tube (11) is caused by means of an exciter arrangement (13) to oscillate with mechanical oscillations, especially bending oscillations. Furthermore, the Coriolis mass-flow/density meter includes means (141, 142) for producing measurement signals (xs1, xs2) representing inlet-end and outlet-end oscillations of the measuring tube (11). An evaluation electronics (2) produces an intermediate value (X′m) derived from the measurement signals (xs1, xs2) and representing an uncorrected mass flow rate. The evaluation electronics also produces a correction value (XK) for the intermediate value (X′m). The correction value (XK) is derived from the measurement signals (xs1, xs2), especially from a second measured value (Xρ) representing a density of the medium and especially likewise produced in the evaluation electronics (2). Moreover, the evaluation electronics (2) produces a measured value (Xm) representing a mass flow rate on the basis of the intermediate value (X′m) and the correction value (XK).

摘要： The measurement transducer includes at least two oscillatably held transducer tubes vibrating, at least at times, during operation, of which at least one transducer tube serving to convey at least a volume portion of a medium to be measured, communicates with a pipeline; as well as at least one transducer element for converting electrical energy into mechanical and/or vice versa. The two transducer tubes are mechanically coupled together by means of at least one, inlet-side, coupling element and by means of at least one, outlet-side, coupling element in such a manner that both the inlet-side coupling element, as well as also the outlet-side coupling element, are subjected during operation repeatedly to deformations which correspond to vibrations of at least one of the two transducer tubes for converting electrical energy into mechanical, oscillatory energy and/or vice versa. The transducer element, especially a transducer element formed by means of a piezoelectric, deformation body, and at least one of the coupling elements, are, at least mediately, mechanically coupled together in such a manner that the transducer element executes, at least in part, oscillatory movements, which correspond with the repeated deformations at least of this coupling element.
