Claim:
1. A vortex flow sensor for a vortex flow transducer for measuring flow velocity of a fluid through by a measuring tube, comprising: a housing having a central axis and a connecting section, on which a shoulder is embodied, said shoulder has a bearing area; a membrane arranged in a plane of said shoulder, whose edge is positioned over said bearing area and is axially spaced therefrom; and a flange shaped support device having a radial edge section and a cylindrical axial section, said radial edge section having an annular front surface facing away from said cylindrical section, an annular rear surface facing away from said front surface and a circumferential surface extending between said front surface and said rear surface wherein: said radial edge section of said flange shaped support device lies with rear surface against said bearing area of said shoulder of said housing; and said cylindrical axial section extends parallel to said central axis within said housing, so that said membrane is supported against an outer circumferential edge of said support device upon application of a predetermined pressure on said membrane.
