    摘要: A coriolis mass flow pick-up is disclosed, which can be inserted into a pipeline and has a fluid to be measured flowing through it during operation. The pick-up includes a single measuring pipe, which has an inlet end and an outlet end, an exciter arrangement, which causes the measuring pipe to carry out at least first bending oscillations, and at least two sensors for sensing movement of the measuring pipe. At least two elongate connection parts, which extend freely essentially parallel to the measuring pipe and whose central axes are displaced from the axis of the measuring pipe, are connected on the input side and the output side to the measuring pipe. The connection parts carry out second bending oscillations in the event of an oscillating measuring pipe, with the result that, by the second bending oscillations of the connection parts being superimposed by the oscillations of the measuring pipe, bending forces and torsional moments at the inlet and outlet ends of the measuring pipe are compensated.

    摘要: A description is given of a Coriolis mass flowmeter, with a measuring pipe oscillating in coupled flexural and torsional modes. Mechanically connected to the measuring pipe is an attachment which is formed rotationally symmetrically with respect to an axis of rotational symmetry and can be induced to undergo the torsional oscillations of the measuring pipe. The attachment is a multipart body comprising hollow profile rails and/or beams with a closed hollow cross section. The axis of rotational symmetry of the attachment runs parallel to the straight line (8) (central axis) defined by the centre points (4a, 6a) of the cross-sectional areas (4, 6) of the inlet and outlet of the measured section, or coincide with this line.

    摘要: A method for compensation for influences, which interfere with the measurement accuracy, in measurement devices of the vibration type, comprising a measurement tube through which a fluid medium can flow and which is caused to oscillate mechanically, acting as an oscillation body, by an excitation unit, whose oscillation behavior, which changes as a function of the flowrate and/or the viscosity and/or the density of the fluid medium, is detected by at least one oscillation sensor in order to determine the flowrate, wherein the material strain in the measurement tube is detected by means of at least one sensor, from which an indicator value for the influence causing the material strain is calculated in order to correct the measurement signal, by signal processing, from the indicator value obtained in this way.
