TURBINE FLOWMETER Russian patent published in 2014 - IPC G01F1/00 

FIELD: measuring equipment.

SUBSTANCE: turbine flowmeter contains a case with a measuring channel, in which between two fairings, respectively the jet-guiding device and the jet straightener, with possibility of axial moving and rotation there is a turbine, and also a unit of signal pickup. On the hub of the turbine there are blades, on which the circular shedding bar is fixed with blades on its outer side and the blades fixed on inside of the mentioned circular body. For providing hydrodynamic equilibration of a turbine at the end of the hub at the opposite side to the inlet there is a circular collar, in which there are longitudinal through channels located against blades, on which the circular shedding bar is fixed. The height of the blades fixed on inside of the shedding bar, is less or is equal to distance between the shedding bar and the circular collar.

EFFECT: ensuring reliability of hydrodynamic equilibration of a turbine in a wide range of measured expenses, also at maximum flow rates, expansion of a range of measurements, sensitivity increase on small flow rates, increase of accuracy of measurements, increase in a resource of work, decrease in pressure losses, simplification of manufacturing techniques of a turbine together with the device for its hydrodynamic equilibration.
