Abstract
A method and apparatus for sampling and optically measuring a selected characteristic of flowing particulate material in which a shelf plate projects transversely into the material stream to collect and hold stationary thereon a quantity of material in the form of pile having an inclined surface exposed at an angle of repose with respect to the plate and over which additional material may flow. After a selected number of optical readings of material flowing over the angled surface, the shelf plate is momentarily partially withdrawn from the material stream such that previously-collected material spills therefrom, and then the plate is returned to the material stream so that fresh material is collected adjacent the material surface.
