TANGENTIAL TURBINE FLOW METER Russian patent published in 2008 - IPC G01F1/06 

FIELD: measuring equipment.

SUBSTANCE: invention can be applied in flow metering in closed delivery pipelines, e.g. in piston pump pipes. Flow meter includes body with metering chamber and tangential meter run mounted inside it on an axis in bearing assembly, and frequency signal detection unit. Body inlet and outlet are tangential against metering chamber and meter run, and together with the metering chamber they form two channels around meter run for alternate-direction flow to maintain meter run rotation in a single direction.

EFFECT: increased measurement precision in direct and reverse flow, simplified signal detection unit.
