Abstract
An impeller for a fluid meter, the impeller comprising a bearing including a central recess suitable for receiving a pivot, and including at the periphery of the central recess, open-ended fluting with adjacent flutes being separated by ribs. Axial passages are distributed around the fluting, with each passage co-operating with at least one flute in such a manner as to facilitate a flow of fluid via the passage to the detriment of a flow of the fluid along the flute. The impeller is applicable to metering fluids loaded with particles in suspension.
