Abstract: The turbine rate-of-flow transducer incorporates a cylindrical body consecutively located wherein in the cocurrent direction there are a first flow straightener, a device for balancing an axial force of the flow, a rotor and a second flow straightener. The device for balancing the axial force of the flow is a truncated cone with passages spaced equidistantly apart all the way along the circumference of the side surface. Each passage is directed so that a projection of its longitudinal axis makes with a plane through an axis of revolution of the rotor an angle between 7.degree. and 20.degree., the vertex whereof points towards the vertex of an angle inclined whereat are the vanes of the rotor. The aggregate cross-sectional area of the passages in the zone of the large base of the means of balancing amounts to 2-6% of the area of flow section at the inlet into the rotor. A pickup located in the body in the zone of the rotor generates a pulse each time a vane of the rotor passes.
