DOWNHOLE FLOW METER Russian patent published in 1995 - IPC

Abstract SU 1329331 A1

FIELD: measuring equipment. SUBSTANCE: measuring unit constructed as jet-directing grids 5 and small turbine 7 set in bearing supports 6 is received in race 4. Additional rotation of the measuring unit is actuated by reverse drive 10 through a magnetic clutch which consists of two clutch members 8 and 9. The speed of rotation of turbine 7 is measured by unit 11. Rotating race 4 is set in additional bearing supports 3 and decreases a static friction moment in bearing supports 6 of turbine 7. EFFECT: improved accuracy of measurements. 1 dwg
