Flumes are the primary devices used to measure flow in open channel systems. There are several factors that are necessary for an accurate measurement, but one of the most basic is the staff gauge. While a staff gauge may seem to be little more than a simple measuring device, there are quite a few options available when it comes to choosing the right one for your flume. Learn about the different types of staff gauges, and discover which works best for your system.

Benefits of Staff Gauges

Before you learn about the different types of staff gauges, it’s best to understand the need for one in the first place. There are a plethora of advanced measuring options available for just about any flume, and staff gauges are among the most low-tech options available. While that may make them seem unappealing to some, they offer a sense of reliability that you won’t find otherwise.

More high-tech solutions can break down over time, but staff gauges are easy to install and operate, and they’re resistant to wear and tear. All that’s required to read them is your eyes, so there’s no learning curve to understanding the measurements. Additionally, they’re extremely cost-effective, as they’re small and easy to install.

Mechanical Gauges

When it comes to staff gauges, mechanical gauges are the most costly option in terms of raw materials, but the installation is fairly simple. They’re typically made of stainless steel, but iron, porcelain and fiberglass options are available as well. The available materials tend to be resistant to erosion and general wear and tear, so mechanical gauges are best used in systems with caustic materials.

Adhesive Gauges

The most cost-friendly option would be applying an adhesive gauge. These gauges are crafted on a flat adhesive surface and can be stuck to the side of a flume as easily as a sticker. In practice, however, it’s necessary to prepare the area a bit first. The mounting surface has to be dry, clean and smooth if you want the adhesive to last. Additionally, it’s essential that no air is trapped under the gauge after application and that all the edges are smoothed down entirely so nothing can enter the adhesive area. 

Molded Gauges

If you’re looking for an entirely new flume system, you don’t have to worry about getting an additional gauge if you opt for a molded staff gauge. While this can add significant costs to your initial flume installation, it’s virtually guaranteed to last as long as your operation does. Because a molded gauge is incorporated into the initial design, it requires no extra labor or installation on your part. It’s ready to go as soon as the flume is.
