The invention relates to measuring equipment and can be used for measuring flow rate and amount of liquids and gases. Turbine transformer of flow rate has body with measuring channel in which between two cowls turbine is placed, with possibility of rotation and axial displacement. Turbine is arranged as hub with one or two end conical collars and attached to it blades arranged with decrease of axial lengths of those from periphery to hub in such way that step overlap in height of blades with account of thicknesses of those is constant or decreases, and has unit for signal takeoff. The invention provides increase of range and accuracy of measurement. At that minimal flow rate at which hydro-dynamical equilibration of turbine takes place is decreased. Decrease of lengths of blades makes it possible to arrange conical collar practically without increase of length of turbine. |
