While there are certainly a variety of advantages to using then-plate weirs, we would be remiss not to talk about some of the cons of this popular flow measurement device.
For most people, the primary disadvantage of weirs is their maintenance requirements. To make sure that your weir-plate functions correctly, you must maintain both the weir crest and weir pool.
There are also several ways in which the accuracy of your weir plate can be affected. If the approach velocity in your system is excessive, it is unlikely that your flume will be able to take accurate measurements. Weir-plates are also very vulnerable to submergence, which can easily impact your normal readings.
Before you install your weir-plate, make sure to consider these drawbacks and how likely they are in your operation.
Different Notch Styles
The last issue we will discuss related to weir-plates and flow measurements is the different notch styles. The style you choose will depend on the type of flow you are measuring.
If you need to measure low flows, for example, then a triangular v-notch weir-plate is your best option. For higher flows, you would need a rectangular, or contracted, notch. You can also choose a rectangular suppressed notch if you want an easier construction process. Other available notch styles include circular, Cipoletti, and proportional.
