Abstract
An instrument comprises a rotor within a stator. The stator is mounted within a casing which forms a gallery which extends circumferentially around the stator, and an inlet which communicates with the gallery at one end and which projects radially outwardly with respect to the stator from that end. Oblique slots are formed in the stator so that fluid flow to be measured is passed from the gallery to the interior of the stator through them. A barrier in the gallery constrains fluid to flow around the gallery in one direction only.
