The invention relates to measuring engineering and can be used, for instance, for measurement of liquid and gases flow rate. Turbine flow rate meter has body with measuring channel in which in sequence are placed jet-directing apparatus with cowl; turbine that is installed with possibility of axial displacement and rotation with device for hydrodynamical equilibration as circular solid of revolution; jet rectifier with cowl and transformer of turbine rotation to output signal. Circular cowl body is installed in turbine concentrically at side of outlet. Technical result of the invention is in provision of reliability of hydrodynamical equilibration of turbine in broad range of flow rates, in particular at maximal flow rates, increase of range of measurements and increase of accuracy of measurements, increase of life time, decrease of head losses. |
