FLUID FLOW METER

摘要

This invention is a fluid flow meter with pulse output proportional to the fluid flow rate. The pulse is transduced by means of a pick-off sensor from the by-passing of a ball which travels in a toroidal passageway at speed close to that of the velocity of the fluid. The fluid flowing into the device follows a loop-shaped circular passageway while the ball travels in a closed circular passageway. Fluid flow propels the ball to revolve continually at a rate directly proportional to the flow rate of the fluid.
