Industry standard rectangular flume used to monitor streams and channels.

Parshall Flume Product Description
The Parshall flume was developed by the US Soil Conservation Service in the 1920’s to measure irrigation water flow. Parshall flumes principle advantages include low head loss, self cleaning capability, and their ability to withstand relatively high degrees of submergence without affecting the rate of flow. Parshall flumes are best used in channels having rectangular cross-sections. Parshall Flumes are the standard for most waste water treatment plant influent and effluents. Parshall flumes can be use with non-full pipes if a suitable transition is provided, however extreme care must be taken when mating Parshall flumes to circular channels. For more information on monitoring Parshall flumes see the FC220, Open Channel Flow Monitor.
