An H-flume is one of the most versatile flumes you can install in your system. While H-flumes are primarily used to measure watershed runoffs and irrigation, they can be used in a wide variety of other applications.
In addition to being able to measure a large range of flows, H-flumes also provide several different mounting options, making them one of the most flexible flume choices in the world. Before you buy an H-flume, you need to learn about your different mounting options so that you can decide which method fits your system. Here are a few tips for mounting an H-flume that you can use to install this tool in your system, and guidance for purchasing this flume quickly and easily.
Installing Below Grade
In many water management operations, it’s necessary to install an H-flume below grade. Fortunately, there are several different methods for installing an H-flume below grade that are both easy and effective. The installation method you use will largely depend on the size of H-flume that you’ve chosen.
For instance, if your H-flume is 2-feet in size, the easiest way to install your flume is to integrate it in a packaged metering manhole. However, it is also possible to install your 2-foot H-flume in the field in a concrete vault.
If you need to install your flume shallow below grade and your H-flume is half a foot, you can integrate it in a fiberglass enclosure.
Above Grade Installation
Other water systems may need to install their H-flume in above grade applications. As with below grade installations, there are several simple ways to install your H-flume above grade.
For H-flumes that are half a foot, you can install your flume in a fiberglass enclosure just as you would below shallow grade. If the H-flume you are installing above grade is three feet, you can install your flume without reinforcement. For example, you could place your flume on a concrete pad, and use threaded rods and anchoring clips to keep it in place.
Any H-flume that is larger than three feet will need to be embedded either in concrete or an earthen channel. This will help to support your flume sidewalls under flow conditions.
Depending on the application of your H-flume, you may need to recess your flume in order to direct your flow correctly. This is most common when using an H-flume for catchment or edge of field monitoring. In addition to directing flow, recessing your flume in a bank can help to prevent upstream ponding.
Another way to direct the flow into your flume is to create a drop by using a vertical discharge pipe that leads into the approach section of the flume. While it’s possible for a drop to impact the accuracy of your H-flume, this can usually be mitigated by increasing the length of the approach section.
Mount Your H-Flume
When you’re ready to install an H-flume in your system, you have a variety of mounting methods at your disposal, both below and above grade. After purchasing an H-flume from Tracom, FRP, you can make use of these tips for mounting an H-flume.
