Description: Article gives a brief methods classification friction reducing in the sensitive element bearings of turbine flow transducers. Possibilities for further use of these methods were analyzed. Mathematical model features of turbine flow transducers with balanced sensitive elements were considered. A technique for determining the sensitive element axial movement based on combining the primary converter hydraulic calculation and the sensitive element motion equations are described.
Keywords: turbine flow transducer, balanced rotor, mathematical model, sensitive element axial movement
