Abstract: Sampling of liquids to isolate discrete samples is accomplished by flowing the liquid through an intermittently actuated diverter from which successive samples flow to different collection locations through appropriate distribution means including a distributor arm movable stepwise to discharge into separate collector lines. Timed actuation of the diverter and distributor is provided by electrical relays and related controls.

Abstract: Sampling apparatus is operated by continuous flow of fluid from a pressurized source through a regulating valve and a flowmeter having dual floats. At intervals determined by the flow rate a pressure-sensitive valve releases accumulated fluid to propel sampled medium from a sample intake to a collection location. Principal uses are in stream monitoring for pollution control, sewage treatment facilities, and industrial waste reduction programs.
