FIELD: invention refers to devices assigned for measuring of consumption of liquid transported along pipeline.
SUBSTANCE: arrangement has body, small turbine, driving roller, transitional and accounting mechanisms. Body has input diffuser branch pipe transferring into spiral feed covering ring guide. Ring guide has blades forming inclined channels. Small turbine is fulfilled in shape of centrifugal open window, whose driving disc has blades on periphery. Blades are directed with their frontal side perpendicularly to inclined channels of guide. At that rear sides of blades have hydrodynamic profile. Lid from the side of driving disc of small turbine is provided with hollow cylindrical console in which driving roller is installed. Driving roller connects small turbine with accounting mechanism through transitional mechanism.
EFFECT: increases accuracy of measurements.
