Do you need more flow capacity than a given flume will handle but are tight on space? If so, one option might be to look at using an EXTENDED HEIGHT flume.

One of the advantages of using a device like a Parshall Flume is that, properly installed and applied, there is NO NEED TO CALIBRATE THE FLUME!  

One of the more misunderstood flumes used to measure open channel flow is the Montana (Short Parshall) flume…but it doesn’t have to be!  The Montana flume is a modification to the Parshall flume where both the throat and discharge sections have been removed…

While it is important to understand the various sections of a flume (converging / throat / diverging) and their associated functions in proper flow measurement, from a practical standpoint it is also important to be able to identify the functional elements of a flume and the…

Foam in flumes or weirs is a headache.  Its a source of measurement error.  Frequently it requires maintenance and monitoring of a flow measurement site.  Generally it's a pain in the neck.  

Fiberglass Flow Metering Manholes from Openchannelflow are a great solution to the problem of needing to measuring below ground flows. The manholes are light weight, corrosion resistant, watertight, and come with flume, weir, or mag meter already factory integrated. The…
