How to Use an Automatic Sampler with Flumes and Weirs

The primary task for the majority of water management operations is measuring both the flow rate and flow level within their system. However, for certain operations, there is also the need to take water sample for quality analysis, and if your operation needs to frequently take water samples, there is almost no better tool than an automatic sampler.

Automatic samplers can take samples from your water management system and store them for later collection without the need for operator supervision, making this the more effective, convenient choice for all of your sampling needs. Learn more about using an automatic sampler in a flume or weir and discover how you can purchase these tools for your water operation.

How an Automatic Sampler Works

The operation of an automatic sampler is actually fairly straightforward. A small tube will be attached to your sampler and will be positioned so that its end is submerged in your system’s water flow. Using suction, water will be drawn into the sampler and collected in a sample tube. By taking frequent water samples using your automatic sampler, you will able to accurately analyze the quality of water in your system.

As mentioned, automatic samplers need no monitoring, and will collect samples from your water system based on whatever schedule your operator sets. In terms of convenience, there is no more convenient option for taking water samples.

Using a Sampler without a Primary Device

Other than the ability to function on its own, the main benefit of using an automatic sampler in your water system is that you don’t necessarily need to use a primary device with this tool. For example, if you don’t have a primary device like a flume or a weir, or if your sampling needs are temporary, you can use a weighted strainer to keep your sampler tube in place instead of using a more advanced installation option.

There are two main advantages to using a weighted strainer with your automatic sampler. First, it can prevent your sample tube inlet from becoming clogged. Second, it can be easily removed when your sampling project has been completed.

Installing a Sampler in a Flume or Weir

Although an automatic sampler can be used without a primary device, most water management systems will possess either a flume or a weir. Fortunately, automatic samplers can be installed just as easily within a primary device. However, instead of using a weighted strainer to secure your sampling tube, you will either connect your tube to the top or sidewall of your flume or weir.

Once the sampler tube is firmly in place, you can attach it to your automatic sampler and start collecting the water samples that your operation needs. Easy, secure installation is one of the many reasons to use an automatic sampler in your water management system.
