Everything You Wanted to Know About Weir Plates But Were Afraid to Ask

Weir plates are perhaps the most useful tool that any water operation can use, particularly those that deal with natural channels. However, despite the popularity of weir plates in water systems across the country, few people are aware of the strengths and weaknesses of this tool, or how to pick the right weir plate for the right job and flow type.

However, when you have the right information at your disposal, you’ll be able to pick the correct weir plate for you. Here is all the information you could want about fiberglass weir plates and information for how to purchase this unique tool for your operation.

The Strengths of Weir Plates

One of the first things to examine when choosing a weir plate for your water management system are the several advantages you’ll get by choosing a fiberglass weir plate.

For starters, weir plates have some of the simplest design of any water management tool, which also leads to very affordable construction costs and straightforward installation. Secondly, weir plates offer several points of measurement that you can take advantage of, and are extremely accurate when they have been installed properly and sized correctly. Finally, you can use multiple weir plates, or compound, if you have different flow rates that you need measured.

Drawbacks to Look Out For

While weir plates offer you a wide range of advantages, there are also some minor drawbacks to consider when you’re trying to select the right weir plate for your water system.

Probably the biggest disadvantage of using a weir plate is the need for regular weir pool maintenance, which can be very difficult for busy water operations. In addition, there are some limitations for where can use weir plates, as they should not be used for flows that take place during cold weather. Other cons of using weir plates include speedy approach velocities, scour downstream of your plate and the possibility for needing a large pool upstream.


Types of Weir Plates to Choose From

Now that you know more about the pros and cons of using a weir plate to measure flow in your water management system, it’s time to take a brief look at a few of the different weir types you have to choose from. The largest difference between weir types is the shape of the crest, which plays a large part in what type of flow that the weir can handle.

For example, most people are familiar with the standard triangle crest weir, which is better at measuring low flows. However, to measure higher volume flows, you would need a contracted rectangular weir plate, and for a range of flows, you should pick a suppressed rectangular weir plate. Additional weir plate types include proportional, circular and Cipolletti.
