Numerous reasons exist for why one may want to cover a weir or flume device. Inflow could be a problem, or an open system could pose dangers to an operator. Perhaps the internal sensor needs extra protection, or the flow is foaming and/or splashing. Whatever the reason may be, weir and flume covers can play a major role in operations. You just have to decide whether you want a transparent or solid cover. Learn about the benefits of each, and discover which is best for your needs.

Solid Covers

As the name would suggest, solid covers are covers in which the inside of the weir box or flume is covered entirely with an opaque material. In most cases, that material is aluminum, stainless steel or sheet fiberglass. If aesthetics matter for your cover, or if your weir box or flume is in a location with a lot of foot traffic, it may be best to opt for a diamond plate cover rather than a plain solid cover.

If you don’t need a diamond plate cover, a solid cover comes with a wide range of functions. The only difference a diamond plate makes is that there’s no way to integrate an observation window. These little windows can be particularly useful, as they come in fixed and hinged options and feature UV- and scratch-resistant polycarbonate.

Transparent Covers

Transparent covers are the more costly option, but they make examining your weir box or flume much easier. The entire surface of these covers can be seen through, so workers and inspectors will always have a full view of the operation. Not only is this more convenient for measurement, but it’s easier to catch potential issues with a full range of view.

The covers themselves can come in several different options. You can opt for a completely clear version or a tinted version if you’d rather have a bit of color for aesthetic purposes. No matter which option you choose, however, the cover will be made from a polycarbonate sheet that’s scratch- and UV-resistant, much like the observation window of a solid cover.

Which to Choose

Determining whether solid or transparent covers are best for your flow system depends on your unique situation. Transparent covers tend to be more expensive, so if you’re looking for a solution on a budget, they may not be the best option. Additionally, they don’t really work well with measuring devices in high-traffic areas, as their clear nature tends to draw attention. Opting for a colored tint can make it more aesthetically pleasing, but that adds an additional cost.

On the other hand, a solid cover comes with its own share of issues. Fully solid covers can make access a bit more inconvenient because you can’t just look inside. Even when you have an observation window installed, the viewing area is notably limited, so you have to consider the location of the observation window extensively before installation.
