For flume and weir applications where the flow entering the device may not be as well distributed as one would like / or where the velocity profile needs adjustment, perforated baffle plates can be a good choice. Used in a series of two or more, perforated baffle plates help…

One advantage that the Cutthroat Flume has always had over other short-throated flume like the Parshall or Trapezoidal was the ability to develop intermediate width flumes for one of the four standard lengths. But what if the standard lengths don’t yield a Cutthroat flume that…

RBC flumes are small, portable long throated flumes designed specifically for use in small earthen channels and furrows. The five flumes are scale models of each other, with each flume possessing a trapezoidal throat varying in size, bc, from 50 to 200 mm [1.968 to 7.874-inches].

Freestanding staff gauges are a good solution to the need to measure level in a flume, weir, or channel. They are also useful in stream gauging or as replacements for other gauges that are damaged or no longer readable.

Reinforced Weir Boxes are a convenient way of measuring seepage flows out of a dam when the pipe is just below grade. Reinforcing the sidewalls of a weir box can allow the structure to withstand the pressures exerted by the soil in shallow burial applications.

Flumes of all styles are used in the measurement and treatment of wastewater. Wastewater applications can be municipal or industrial in nature and their content can be sanitary (including mixed) or non-sanitary.

The video below highlights the ability of the H Flume to measure a wide range. The ability to accurately measure a wide flow span makes the H flume uniquely suited to edge-of-field installations. Edge-of-field monitoring serves as a bridge between larger watershed studies and…

Stainless steel is often viewed as the material of choice for Parshall flumes when severe corrosion is expected or when abrasion is a concern. For Parshall flumes, the split between T-304 and T-316 stainless steel is about 60 / 40, with more flumes being constructed from T-304.

Although initially developed to measure runoff from watersheds and experimental plots, the H Flume has proven to be quite flexible in its mounting configurations. For below grade applications, HS and H Flumes up to 2-feet in size can be:

Open feedlots are common throughout North America. Although they provide an economical way to feed and raise a variety of livestock, such operations generate large quantities of runoff that have considerably elevated nutrient levels (ammonia, nitrogen, and phosphorous) as well as…

Edge-of-field (sometimes referred to as catchment) monitoring is where flow from a particular field is routed to a monitoring station located at the edge of the field to allow for the characterization of the runoff flows. Edge-of-field monitoring is used in a number of…

The H Flume was developed to measure runoff in small experimental plots and agricultural watersheds. Like a weir, the H flume develops a backwater effect at higher flow rates. In low gradient applications, this backwater effect can cause flooding.
