Abstract
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.
