Selecting a Flume For an Existing Pipe or Channel

Open channel flow measurement can be a challenge in applications that require the placement of a flume in an existing pipe or channel. While most everyone is familiar with Parshall Flumes, in many cases, there are other flume options that can provide for equal or better accuracy and are better suited for a particular pipe…

Parshall Flumes – Free vs. Submerged Flow

As often as we use Parshall flumes for open channel flow measurement, it is important to understand “free versus submerged flow” conditions; as it greatly impacts the accuracy of the installation…or the lack thereof. While any primary device could be affected by submerged flow conditions, there isn’t much data to be found on the topic.…

Flume Selection Guidance

One of the most frequent requests that we get from civil engineers during WWTP design is for flume selection guidance. While there are many complex aspects that need to be considered in flume selection and outfall channel configuration, there are a few basic considerations that can be evaluated to streamline the process.
