Insulated flume covers from Openchannelflow can help to provide better flow data during cold weather periods by eliminating frost / ice build up on the flow meter sensor as well as insulate the space above the flume.  When used in conjunction with a strip, pipe, or immersion…

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…

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…

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…

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…

One of the problems that operators face is trying to meter a line that is located in a street / parking lot / or other vehicle traffic area. While Packaged Metering Manholes provide all-in-one primary device integration with easy operator access in one structure structure, the…

YouTube user Pener Pã has posted an interesting video showing the installation of a Rectangular Weir Plate with End Contractions into a natural channel. The video opens with the fabrication of the plate and its transportation to the installation site...

Those responsible for collecting and reporting industrial pretreatment discharge information (typically flow, pH, BOD, and temperature) are rarely dedicated professionals. Almost always, environmental discharge monitoring is just one of a laundry list of job duties they have to…
