If you’re not familiar with what these devices can do, it’s a good idea to get an idea of their benefits to help you make the decision for your new operation. Check out this overview of Parshall flumes, learn the basics of why they are so popular, and discover where you can get more information or place an order.
Parshall Flume Purpose and ApplicationsThe Parshall flume was originally designed to create a new type of flow management primary device that would not be limited in the same way that rating flumes and weirs are. Because of its unique design, it works for a wide range of different applications, making it one of the most popular options all over the world for flow management systems. The Parshall flume is often used outdoors to measure irrigation and stormwater runoff, dam seepage, and more. They can be used for wastewater treatment facilities and other industrial operations. Really, they work for just about any situation requiring flow measurement.
Benefits and Drawbacks of the Parshall Flume
The Parshall flume carries with it many benefits that make it one of the more popular designs for a variety of applications. Indeed, the popularity of these flumes is one of the biggest benefits. Since they’re in such wide use, most operators are already familiar with their use. That means you don’t have to spend extra time training workers. Next, they are resistant to obstructions from solids, and to submergence. That reduces their need for maintenance. Third, they are very easy to connect to pipes.
There are fewer downsides to this kind of flume, but it’s still important to understand what they are. If you choose a smaller size one, they can still be vulnerable to clogging. This, however, can be an issue with any flume of an improper size. More importantly, because they require a drop in elevation, they can be tough to retrofit.
When Not to Install Parshall Flumes
As popular and widespread as they are, there are certain situations where a Parshall flume is not the right choice. If, for example, your system has a lot of low flow, a Parshall flume may not handle it as well as you’d like. They also require a fairly significant amount of space to install so if your installation area is a tight fit, they might not be the right choice. They also cannot be installed in a flat channel.
