Abstract
An internal gate rotary vane fluid meter which has markedly improved performance as a result of precise control over the geometry and dimensions of the rotating elements and the fluid flow path. In particular, the outer diameter of the gate is maximized and the inlet and outlet passages of the meter are shaped to perpendicularly intersect the rotor vanes when the vanes are sealing against the respective ends of the meter crescent. Furthermore, the inlet and outlet passages each have a total cross-sectional area substantially equal to a vane area to provide substantially constant fluid velocity.
