Fiberglass Cutthroat Flume

cutthroat flume

There are several different styles of flumes that you could choose to manage the flow in your system. However, perhaps the most interesting is the Cutthroat flume. These flumes have been in existence since the 1960s and were designed to effectively measure flow in flat channels.

If you’re not familiar with the Cutthroat flume, then you might not be aware of the innovative design that makes this flume so different from other flume options. Read how the Cutthroat flume differs from other flow management tools and find out if this flume type is the right choice for your system.

Missing Throat

There are several characteristics that make the Cutthroat flume different from other flumes, but the most noticeable is its lack of an extended throat. In fact, this is where the Cutthroat flume gets its name because it has literally cut out the throat that you would find in other flumes.

The lack of a throat provides the Cutthroat flume with several advantages. For instance, it is capable of measuring a variety of flow rates. In addition, Cutthroat flumes are much less at risk for sedimentation than flumes with longer throats. If you want to avoid sedimentation as fully as possible, consider choosing a wider Cutthroat flume.

Flat Floor

Another factor that makes the Cutthroat flume unique among flumes is its flat floor. Having a flat floor makes the Cutthroat flume extremely useful as a retrofit device, meaning this flume can be installed directly in the channel floor without the need for extensive adjustments. For comparison, the Parshall flume requires either a downstream channel change or elevation before it can be installed in a channel.

Also, unlike other flume types, the Cutthroat flume does not need adjustments in order to achieve supercritical flow. This means you can install a Cutthroat flume in your system and start taking consistently accurate measurements almost immediately.


Perhaps the biggest advantage of a Cutthroat flume is that it can be used in an almost unlimited variety of applications. Whatever your flow measurement needs, the Cutthroat flume makes a superb choice.

For example, because of its resistance to sedimentation, the Cutthroat flume can be used in wastewater and industrial applications where solid debris is likely to be present. A few of the other common uses of a Cutthroat flume include surface water and irrigation flow management, proportional flow splitting, and mine dewatering. If you have a flat gradient in your system where you need to measure and manage flow, you should strongly consider using a Cutthroat flume.
