This turbine-type flowmeter is intended to be used with means, known in themselves, for annuling any non-axial component of the absolute velocity of the fluid at its arrival at the measuring turbine. The flowmeter comprises a detector element for detecting the non-axial component of the absolute velocity of the fluid at its exit from the turbine, and a corrector element acting on the speed of rotation of the turbine, and actuated by the said detector by the intermediary of a servo-control device such as to annul the non-axial component of the absolute exit velocity of the fluid.
