Above Ground Flume Enclosures
To protect flumes in above ground applications, Openchannelflow has developed a range of fiberglass enclosures that factory integrate small flow measuring flumes. Enclosure integration: Safeguards the installation - restricting access to the flume and flow meter Reduces the…
Water Conservation and Nested Parshall Flumes
One of the nice things about the Parshall flume is that it lends itself well to flows that shift dramatically over the life of the flume. In applications where water conservation has occurred and the flows that a Parshall flume was designed are no longer occurring, a…
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…
