Abstract
A Coriolis flow sensor with a Coriolis tube that is fastened in a housing and that can be excited with a certain frequency, wherein a balancing mass (inertia) is arranged with rotational flexibility between the tube fastening and the housing. In particular, a spring steel plate is used for providing a connection rigidity between the balancing mass and the housing, which plate comprises a fixed portion and a movable portion cut out from the fixed portion, wherein the incisions are formed such that the fixed and movable portions are interconnected via resilient plate portions, which resilient plate portions are in particular elongate strips lying in one line and realizing a rotational flexibility (torsion), while abutments are provided which limit the amplitude of movements of the balancing mass.
