ABSTRACT:
A liquid flow meter of a rotary positive-displacement kind comprising a rotor and an idler mounted in a housing having an inlet and an outlet port. The rotor has blades which are swept around the housing by the fluid and the idler has pockets within which the rotor blades are returned from outlet to inlet in a fluid seal. There are four blades and three pockets, the idler being geared to the rotor so that the idler rotates four revolutions for every three revolutions of the rotor. With this arrangement the blades twist very little while in the pockets and turbulence and drag is consequently reduced, leading to greater accuracy.
