Types of Flumes For Flow Management

Flumes are some of the most versatile, accurate flow management devices in the world. Whether you need to measure flow in an outdoor setting or in an indoor industrial application, you can find a flume that will more than meet your needs.

Because there are so many different styles and classes of flumes, however, it can be a little tricky to know which device is right for you. Here is a quick guide to some of the different flume styles that you can choose from when picking the right flow management device for your operation.

Short- vs. Long-Throated Flumes

Although flumes come in several different styles, there are actually only two classes of these devices: short-throated and long-throated. Both of these classes have their advantages, so let’s take a look at each so that you can decide which is right for you.

One factor to keep in mind is that the descriptions short and long don’t actually refer to the size of the flume, but rather to how the flow is controlled within the device. A short-throated flume controls flow in a very small section of the device to create specific measurement results. With a long-throated flume, the throat must be long enough that parallel flow lines are possible. This difference in flow control makes long-throated flumes slightly more accurate than short-throated flumes.

Different Styles of Flumes

Now that you know about the two different classes of flumes, let’s take a look at the different flume styles. The Parshall flume is by far the most popular flume style, both because it can be installed in almost every application imaginable and because it is self-cleaning, which reduces maintenance needs. This flume is also available in in several variations, including the Cutthroat flume, which removes the throat section.

H-flumes are a popular style for operations where accuracy is of the utmost importance, whereas trapezoidal flumes are perfect for applications where solid matter in the flow is a concern. Some other available styles of flume include RBC flumes and Montana flumes.

Choosing Your Flume

If you need to install a flume in your flow management operation, there are a few things that you can keep in mind to help you choose your device. First, you need to think about the characteristics of your flow. For instance, certain flumes only work well with a consistent flow rate, while others can handle both low and high flow rates. Second, consider if there’s solid debris in your flume. If so, you will want a flume specifically designed to pass solid matters so that you won’t have to worry about blockages.

You should also think about where you plan to install your flume. Certain types of flumes, such as the RBC flume, can easily be installed in a natural channel, whereas other flumes can only be installed in these applications after certain adjustments have been made.
