Measuring Pipe Flows with Trapezoidal Flumes
Originally developed to provide both low-end sensitivity and wide flow, Trapezoidal flumes have expanded beyond the agricultural applications they were designed to measure a wide range of pipe flows. Trapezoidal flumes can be found on pipes measuring: Dam…
Advantages of Parshall Flumes
Used to measure municpal sewage, industrial effluent, dam seepage, storm water, and irrigation / agricultural flows, the Parshall flume is the best known and most widely used primary device monitoring water in open channels and non-full pipes. Parshall flumes offer a number of…

The Secondary Point of Measurement (Hb) of a Parshall Flume
Under free-flow conditions, short-throated flumes control flow in a region of the flume that produces curvilinear flow. As such, there is only one point of measurement at which the level-to-flow relationship holds. This primary point of measurement, Ha, occurs in the…

Using a Parshall Flume for Chemical Mixing
While we often thing we seen it all, we are continually amazed by users. YouTube user Sidney Seckler has posted a video showing an unusual use for a Parshall flume: Chemical Mixing! Alum is added (as a coagulant) to the flow upstream of the flume. The flow is…
