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 fluid meter has a gate with at least two pockets which rotates at the same velocity as a rotor having the same number of vanes and the inner diameter of the rotor vanes is controlled to provide a properly sized orifice between the vane inner diameter surface and the gate hub so as to provide a driving torque to the gate due to the passage of the vanes through the gate pocket, the gate driving torque being balanced to match gate retarding torques due to fluid dynamic losses, friction of the gate drive train and friction of the gate bearings.
