Abstract

A fluid flow meter of the type having a vaned rotor mounted in a measuring chamber is provided with a series of inlet apertures arranged around the chamber with each aperture having one face (84) which extends sufficiently in the circumferential direction as to meet the opposite face (90) of the adjacent aperture. Since almost the entire periphery of the chamber wall is formed by apertures the collection of inflowing fluid is maximized while the apertures serve to direct at the rotor vanes (66) jets of fluid which are placed for maximum efficiency.
