ABSTRACT:
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.
