JET AUTO-GENERATING FLOW METRE Russian patent published in 2010 - IPC G01F1/20 F15C1/22 

FIELD: machine building.

SUBSTANCE: jet component (1) of auto-generating flow metre consists of feed nozzle (5), working chamber (6), control nozzles (10 and 11), receiving channels (12 and 13), divider with concave deflector (9), drain channels (14 and 15) and channels or back feed (16 and 17), also of converter (2 and 3) of jet pulses into electric signal connected with facility (4) of signal isolation proportional to frequency of pulsation. A local bell mouth (18) ended with ledge (19) is made at input of feed nozzle (5). Angle of incline of bell mouth to axis of the feed nozzle is 30-45°, while height of the ledge is not less, than half of feed nozzle width.
