Abstract
A flow sensor includes a measuring tube, made of essentially non-ferromagnetic material, for guiding the fluid, a magnetic circuit arrangement arranged on the measuring tube for producing and guiding a magnetic field, which induces in the flowing fluid an electric field, and measuring electrodes for sensing a voltage of the electric field. Additionally, the flow sensor includes an essentially rigid support frame for holding the measuring tube and for holding an electronics housing connected to the flow sensor, wherein measuring tube and support frame are mechanically coupled together on the inlet and outlet ends. For holding the measuring tube in the support frame, at least one connecting element is provided, which is attached to a first end of the measuring tube and to a first end of the support frame corresponding to such end of the measuring tube. The at least one connecting element is so formed and so arranged in the flow sensor, that it is essentially axially flexible, as compared to support frame and measuring tube, in the direction of the longitudinal axis of the measuring tube.
