摘要

New counter of the turnstile type essentially characterized by comprising said counter on the one hand a tubular envelope bounded internally by a cylindrical surface and on which it is arranged on the arrival side of the fluid from which it is desired to measure the volumetric flowa fixed helical vane stabilizer destined to be printed at fluid that passes through a rotation movement in a fixed direction relative to the general axis of the counter whatever the flow rate of that fluid and on the other hand a measurement device comprising a turnstile mounted in free rotation around the general axis of the counter continuation of said stabilizer moving the axis of said turnstile a count-turns for the recording of the volume flow of the fluid passing through the counter, said counter being characterized by the fact that the turnstile is constituted by a fin turbine designed so that it can significantly deviate the fluid from the trajectory that it has been imposed by the stabilizer and thus picks up an important power at the expense of that fluidizing on the other hand said turbine in dependence on a regular device system comprising a frame organ destined to create a variable resistive torque on the turbine and an organ located in the rear part of said turbine to detect the residual rotation speed of the fluid at the exit of the turbine and regulate the variation of the resistant torque of the frame member as a function of said residual rotation speed of the fluid to continuously redirect and maintain said speed in a then, the counter is turned off in the maximum performance conditions of the turbine, and in this case the speed of rotation of the latter is proportional to the volume flow of the fluid passing through the counter.
