ABSTRACT:
The device measures the flow of a fluid and comprises a rotor 16 having vanes which is driven in rotation by a stream of fluid in a sealed housing 11 having a circular cross-section and provided with a supply nozzle and a discharge nozzle for the fluid which are in alignment and disposed tangentially to the rotor so that the fluid stream issuing from the supply nozzle encounters the vanes 1 in a direction perpendicular to the axis of rotation 17 of the rotor. The rotor 16 has two lateral flanges 16a, the vanes, the flanges and the housing defining, apart from a clearance for permitting the rotation of the rotor, a series of compartments which communicate by way of that clearance with two lateral chambers 12a of the housing. The invention is in particular applicable to the measurement of small flows of gas under high pressure.
