Trapezoidal Flumes

For Low Flow Applications
Trapezoidal flumes were originally designed by the U.S. Soil Conservation Service to measure flows in irrigation channels. Today, however, they are used in a growing number of sanitary and industrial sewer applications with very low flow rates. Trapezoidal flumes are a great solution for low flow instances because they come in various sizes and have several primary advantages.

Trapezoidal Flume Sizes & Options

Trapezoidal flumes are typically available in 10 different sizes based on throat width and geometry. They are an excellent choice where flows vary, the channel is flat, or there are high levels of debris load in the flow stream.

The most common trapezoidal flumes include the following sizes and styles for the recommended flow rates:

Trapezoidal Flume Advantages

For low flow applications, trapezoidal flumes are very beneficial. Compared to other flumes, trapezoidal flumes exhibit three main advantages:

Trapezoidal Flume Applications

Trapezoidal flumes are a great option for projects with low flows, such as various sanitary and industrial sewer applications. These types of flumes are typically seen in:

  • Dam Seepage
  • Irrigation Canals
  • Watershed Monitoring
  • Ditch and furrow Flows
  • Monitoring Industrial Discharge
