ABSTRACT:
A flow sensor particularly adapted to the measurement of fuel flow to internal combustion engines, but not limited thereto, the sensor including an annular raceway intersected by a tangentially disposed inlet jet nozzle and an outlet opening disposed immediately downstream of the inlet jet nozzle and radially offset therefrom whereby the initial fluid jet passes the outlet opening before radial distribution in the raceway, then circles the raceway and discharges into the outlet; the raceway receiving a ball having a density corresponding to the fluid for continuous rotation at a speed corresponding to the speed of the fluid movement in the raceway; the raceway having a traverse optical sensor to detect rotation of the ball; a chamber having a diaphragm exposed to flow through the inlet, the chamber assuming an expanded condition during increased flow and contractable on initial minimum flow to effect momentary supplemental flow to the raceway, and aid in maintaining movement of the counter ball.
