Open channel flow devices come in several shapes, sizes and styles, but when it comes to reliability and accuracy, there’s simply no beating a Parshall flume. Parshall flumes are used so widely and have been around for so long that it can be easy to take for granted just how versatile these flumes actually are, making it a good idea to brush up on these devices. Here are a few Parshall flume facts that everyone in the open channel flow industry should know, including how to install these flumes.
Where Can You Use Parshall Flumes?
When you’re learning about Parshall flumes, the most important topic is where you can use one of these devices. Versatility is the main reason that Parshall flumes have remained so popular over the years, and there is almost no limit to where you can install this flow management tool.
Typically, you’d find a Parshall flume in an industrial application. For instance, these flumes are frequently used to monitor flow in sewage treatment plants and are also suitable for monitoring industrial discharges. Thanks to their flexibility, you can also use a Parshall flume in a number of outdoor settings. If you need to measure flow in a stream or at the edge of a field, for example, a Parshall flume just might be the tool for the job.
What Are Parshall Flumes Made From?
Now that you know exactly where you can install your flume, it’s time to discuss what materials you can use for your device. In systems where the flume needs to be transported from place to place, aluminum is a popular flume construction material because it is lightweight. On the other hand, applications that need durability will often choose stainless steel.
While there are a lot of material choices for your Parshall flume, fiberglass is usually the best option. For starters, fiberglass is highly durable and stands up to even the toughest situations, including sewage flow monitoring. Fiberglass is also very cost-effective, which can be a concern for many open channel flow operations.
Installing Your Flume
Some of the most important Parshall flume facts are related to installation. In general, Parshall flumes can be installed very quickly and easily, particularly if you follow a few simple steps. Your primary installation goal should be keeping your flume centered in the channel so that it captures all the flow. If any flow manages to bypass your flume, it will make it impossible to take accurate flow readings.
While Parshall flumes are resistant to submergence, you should make sure the floor is at the right height to prevent this phenomenon. During installation, you should brace the inside of the flume so that it doesn’t warp, and you may also want to add support to the exterior of the flume so that it stays centered.
