Abstract
The disclosed orbital ball flow detectors have an exposed ball-sensing electrode near or along the path of the orbiting ball, and a return electrode. The ball's cross-section is much larger than the sensing electrode, which is closely over-shadowed by the ball as it orbits past the electrode. Unusually large signals are provided when the ball is of insulation and the flow to be monitored exhibits some electrical conductivity. Where the ball orbits along a conductive track and is of metal, it acts as a switch when oribiting past the sensing electrode.
