FIELD: measuring engineering. SUBSTANCE: piece is set free with its controlled surface on nozzle, through which working fluid is fed, amount of which provides free suspended state of piece in stream. Then value of controlled surface lift over nozzle cut is measured. After working fluid is fed, piece is mounted on nozzle and value of controlled surface lift is compared with reference value. EFFECT: control productivity increase. 2 dwg
