Parshall Flumes are used in sewage treatment plants as well as industrial and municipal sewers. When it comes to fixed flow monitoring installations, the Parshall Flume is one of the most widely-used flume types. The special shaped open channel flow section is often installed in ditches or canals to measure flow rate.

Parshall Flumes are sized by throat width and conform to standardized dimensions published in the U.S. Department of the Interior, Bureau of Reclamation.
