The device comprises a tubular stator intended to be fixed in a pipe, so as to be traversed, in use, by said stream of fluid, and in which there is axially mounted a rotor which has a central hub from which extends a plurality of blades and which is capable of being operated in rotation by said stream, like a turbine, at a velocity variable according to the flow rate, and at least one permanent magnet integral with the rotor, disposed eccentrically with respect to the axis of rotation of said rotor. Fixed to the hub of the rotor is a shaped support bush mounted rotatable about a fixed pin or shaft which extends, projecting in the opposite direction to the operational direction of flow of the stream, from a central support integral with the axial outlet portion of the stator. The magnet is held in a housing defined between the support bush and the rotor.

Device for measuring the flow rate of fluids

The actuator comprises: an actuator member which is moveable relative to the structure and can perform an actuation movement in one direction and a return movement in the opposite direction, an electric motor including a rotor portion which can translate from a first, rest axial position to a second, working axial position as a result of an energization of the stator and against the action of a spring, a gear transmission which is coupled to the actuator member and can be coupled for rotation with the rotor portion when the latter is in the working axial position in order to bring about an actuator movement of the actuator member, and a stop device with a retaining member which can adopt an inactive condition and an active condition and an active condition in which it permits and prevent a return movement of the actuator member, respectively. The retaining member is operatively coupled to the rotor portion of the motor in a manner such that it can adopt the inactive condition and the active condition when the rotor portion adopts the rest position and when it adopts the working position, respectively.
