    摘要: The disclosure relates to a Coriolis mass flowmeter with an oscillatable straight measuring tube consisting of a corrosion-resistant metal, in particular of titanium or a titanium alloy, to which are attached mounted parts connected directly to the measuring tube for the implementation of the Coriolis measurement principle. Furthermore, stabilizing elements running parallel to the measuring tube are coupled to the measuring tube via mounted parts connected directly to the measuring tube, the mounted parts and the stabilizing elements consisting of a metal other than that of the measuring tube. The stabilizing elements are manufactured from a second material which possesses a coefficient of thermal expansion adapted to the metal of the measuring tube. The mounted parts connected directly to the measuring tube are manufactured from a third material which possesses a higher coefficient of thermal expansion than the metal of the measuring tube.

    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.
