If you operate a water management system, then you’re probably very familiar with thin plate weirs. Thin plate weirs are some of the most useful flow management tools that there are, especially for natural channel applications, and many water management systems would be far less effective without this useful product. However, what you might not realize is that thin plate weirs can actually be produced in alternative styles, adding to their already large utility.
Anyone considering the use of a thin plate weir in their water system would be well served to examine a few of these alternative styles. Learn more about the alternative types of thin plate weir that you could use in your water management system and find out how to purchase these products.
Circular
Unlike traditional thin plate weirs, which are meant for natural channels, circular wheels are meant to be installed in man-made pipes in order to effectively manage flow. The biggest advantage of choosing a circular weir for the pipes in your system is that it can be installed regardless of the size of your pipes. Typically, a circular weir will either be fitted to the end of your piping or will mounted inside of a pipe.
Cipoletti
For most weirs, side contraction can be a problem, interfering with flow and possibly affecting the accuracy of your system’s measurement. In order to address the risk of side contraction, the Cipoletti weir was produced. A Cipoletti weir has a much larger notch that is trapezoidal shaped instead of the usual V-shape. In addition, the outer sections have a steeper slope that has been intentionally manufactured in such a way to combat side contraction.
Proportional Notch
The relationship between discharge flow and head is one of the most important considerations when using a thin plate year, and for systems looking for a linear relationship between these two factors, the Proportional Notch weir was designed and manufactured. Proportional notch weirs use a notch created by parabolas on each side. The higher you go on the notch, the closer the parabolas get to each other. It is through the use of these unique parabola shapes that the Proportional notch weir is able to maintain the linear discharge flow and head relationship.
Compound
For certain water systems where a hydraulic structure is used, a great decision is to install two different types of weirs, which is known as a compound weir. When you use a compound weir, you would install weirs at two different points in your system, one to measure minimum flow and one to measure maximum flow. Compound weirs are useful for measuring versatility and for larger systems that deal with multiple flow types.
