Turbine flow rate meter has body with measuring apparatus in which in sequence are placed flow-directing unit arranged as ribs placed on front cowler, turbine installed with possibility of axial displacement and rotation that is hub with device for hydrodynamic equilibration as one or two end conical collars with blades fixed there and circular body of resistance, flow guide with reverse cowler, transformer of rotation of turbine to output signal. In the end part of ribs of flow-directing apparatus at side of turbine depression is provided (for instance in circular form) with inner diameter smaller compared to inner diameter of circular resistance body and outer diameter is larger than outer diameter of circular resistance body, at that screw separation of blades of turbine placed between circular resistance body and hub is larger or smaller compared to screw separation of blades of turbine at outer side of circular resistance body and length of circular resistance body is larger that axial length of blades of turbine. |
