Abstract
A composite wastewater sampler includes a flow-through-chamber having an inlet port and an outlet port with a path between them that gradually increases in depth and width and then decreases in width. It is shaped to cause fluid to (1) flow from the inlet port; (2) drop to a lower level of flow within the flow-through-chamber; (3) gradually adjust in cross-sectional shape to the outlet port; and (4) flow back into a wastewater pipe. A sampling nozzle extends into the flow-through-chamber adjacent to the inlet port and within the path of the downwardly flowing wastewater so that wastewater exiting the port contacts the nozzle and flows downwardly across it.
