Cutthroat Flumes are ideal for measuring water flow rates where an easily portable, completely collapsible flume is needed. Common uses are in stream surveys, evaporation studies, drainage surveys, and well pumping tests.

These stainless steel, collapsible flumes can be set up in minutes and are ideal for a broad range of field applications. When the job is finished, the flume (weighing only 6-15 lb.) can be disassembled and put into a carrying case. The name, "Cutthroat" comes from the fact that there is no parallel throat section in these flumes, as in Parshall flumes.

In the Cutthroat flume, the throat width can be changed from one to eight inches by interchanging the top and bottom pieces with a conversion set while continuing to use the same sides. Thus, flows ranging from 2 1/2 to 1000 gallons per minute may be measured. Wingwalls may be added to divert the stream into the upstream convergent section of the flume. The 19 inch wingwalls are in two sections, as illustrated in the picture. Once the upstream staff gage is read, it is a simple calculation to arrive at either the gallons/minute, liters/second, or cubic feet/second flowing through the flume.
