TURBINE FLOW METER Russian patent published in 2009 - IPC G01F1/12 

FIELD: physics, measurement.

SUBSTANCE: invention is related to metering equipment and may be used for measurement of liquid and gas flows. Turbine flow meter comprises body with metering channel; small turbine installed with the possibility of rotation and axial shift; input jet-directing apparatus with device for small turbine hydrodynamic balancing, jet rectifier with output fairing, unit for signal pickup. Device for hydrodynamic balancing of small turbine is arranged in the form of fairing with longitudinal grooves on side surface, bases of which in fairing output part are arranged at the angle to axis of measuring channel in fairing end and are located along circumference with diameter that is less than diameter of opposite end of small turbine hub.

EFFECT: provision for hydrodynamic balancing of turbine in wide range, also at maximum flows, increase of operational resource.
