A Fluid turbine flow meter, including a measurement chamber, a turbine body that is displaced axially, as a function of the fluid flow rates, between a high position and a low position in the measurement chamber and having a rotation axis, a centering bearing for the rotation axis in the measurement chamber that has a longitudinal body with a longitudinal passage supporting and passed through by the rotation axis, the rotation axis pivoting by being held axially in the measurement chamber, by a first axial end stop in the high position and by a second axial end stop in the low position, the centering bearing having, in the longitudinal passage, at least two cylindrical longitudinal support centering walls for the rotation axis.

Fluid turbine flow meter with centering bearing

The invention concerns a fluid turbine flow meter including a rotatable longitudinal body of a turbine equipped with longitudinal blades and regularly distributed support arms of the blades connecting the blades to the rotatable body of the turbine, where each blade has on the support arm a plurality of separate longitudinal thrust members the cross sections of which are adapted to receive the thrust of the fluid jet when the blade is active and to allow circulation of fluid between the thrust members when the blade is inactive.
