ABSTRACT:
The disclosed orbital ball flow detectors include a photoelectric ball sensor applicable to both axial-flow and toroidal forms, wherein reflection occurs at the ball. Also disclosed are photoelectric ball sensors of both the transmission and reflection types in which the light path extends through pellucid material of the passage means that forms a track against which the ball bears as it orbits. There may be a swirl in the flow pattern of the fluid; and then multiple pairs of orbital ball flow detectors, each carrying part of the total flow and having mutually opposite orbit directions, provide improved accuracy.
