Abstract: A vortex flow transducer for measuring the flow velocity of a fluid flowing in a measuring tube as well as to a vortex flow sensor for the vortex flow transducer. In such case, the vortex flow sensor includes a housing having a central axis and a connecting section, on which a shoulder is embodied, which has a bearing area. In a plane of the shoulder a membrane is arranged, whose edge is positioned over the bearing area and is axially spaced therefrom. The vortex flow sensor includes, furthermore, a flange shaped support system having a radial edge section and a cylindrical axial section, wherein the radial edge section lies with its surface against the shoulder of the platform and the cylindrical axial section extends parallel to the central axis, so that the membrane is supported against the support system upon application of a predetermined pressure on the membrane.
