ABSTRACT:
In a vortex chamber flow meter, a bearingless annular rotor rotates about an axis in a cylindrical operating chamber. The chamber is enclosed in a jet ring within a meter housing. Liquid enters the housing and flows to a plurality of circumferentially spaced ports in the jet ring, directing flow through conduits into the vortex operating chamber tangentially. Liquid flow exits the vortex chamber axially through a central aperture. Optical sensing means respond to markings on the surface of a rotor moving past a selected position. The meter is constructed to effectively offset the entry of the liquid into the vortex chamber. The centerlines of the ports define a plane which is positioned to be off center from a plane bisecting the vortex chamber in the axial degree of freedom. The offset is in an axial direction away from the exit.
