Quality State-of-the-Art Technology


Why use our flumes for wastewater measurement and treatment? They are:

  • Financially viable and durable. Using a fiberglass flume means that you’ll have a less expensive, yet stronger, flume than stainless or galvanized steel, or even using concrete flumes.
  • Durably Constructed – Our flumes are created with exact dimensions, with top spreaders factory installed. The flumes contain lightweight laminated foam ribs that reduce wall and floor deflection more consistently than embedded angles.
  • Created with Smooth Surfaces – The white gelcoat reduces silt buildup and organic debris. It also heads in the reading of the gauges and instrument regulation. The gelcoat makes cleanup easier.
  • Easy Installation – Our flume products have bracing and heavy ribbing, which offers better stability, and can be used along or as concrete liners.

Parshall Flumes

The most widely known flume, and still the most widely used for permanent installations. Used in monitoring sewage, plant effluent and irrigation water. Available in sizes 1 inch through 12 foot.

RBC and Step Flumes

RBC and Step Flumes are often used in agricultural research this they are long-throated flumes. Therefore, they are also used for water resource allocation, water runoff studies, and water shed management.

Palmer-Bowlus Flumes

These flumes are used in the sanitary field. They measure flows in manholes and also are used in pipelines and temporary installations.

Cutthroat Flumes

While these flumes are similar to Parshall flumes, the bottom of them are the same elevation as the channel invert throughout the entire length of the flume.



Trapezoidal Flumes

Developed for irrigation, trapezoidal flumes have proven their effectiveness by the Soil Conservation Service and Department of Agriculture – both to monitor flows in furrows and in sloping irrigation ditches. Now they are increasingly popular for applications where low-flow measurement is required.
