Although many people are unaware of this fact, flow measurement is one of the biggest responsibilities for farming operations. Whether these measurements are a requirement for water rights or are needed for irrigation purposes, it’s important to use the right tool, and the two most popular flow measurement devices for farm applications are flumes and weirs.
If you’re trying to decide which device fits the needs of your farming operation, it’s a good idea to learn more about both so that you can be certain you’re making the correct decision. Here is some information about flumes and weirs for farming applications that can help you pick the device that meets your needs.
Which is More Accurate?
When it comes to choosing a primary flow measuring device for farming operations, the most important factor is picking an option that provides accurate readings. In this category, the obvious winner is a flume.
While weirs are certainly accurate in most situations, they may not be the right choice for measuring water rights or irrigation flows, as these flow rates can be inconsistent. On the other hand, if you install a flume, you should be able to take accurate readings time and again, regardless of the style of flume you choose to install.
Resistance to Solids
Depending on your farming operation, you may need to install a flow measurement device that is resistance to solids. If solids are a concern in your measurement channel, then the right device for you is once again a flume.
Many styles of flume are produced with flat floors that are designed to easily pass solids. When you install one of these flumes, you won’t have to worry about blockages that interfere with the accuracy of your measurements.
Instead of being flush with the channel, weirs are installed slightly above the channel floor, which can allow sediment to make its way into the weir pool. As sediment builds in the pool, you will see increasing errors in your readings.
Picking Your Materials
One of the biggest advantages of using flumes and weirs for farming applications is that you can have your device constructed out of almost any material you wish. For instance, if you’re installing a weir on a temporary basis, it’s possible to use an affordable material like plywood that wouldn’t be suitable for permanent installations.
However, if you want your flume or weir to last as long as possible, the best material choice is fiberglass. Because it is resistant to corrosion and UV damage, fiberglass is the ideal material for outdoor farming applications. With a fiberglass flume or weir, you’ll be able to take accurate readings for years to come.
