Parshall Flume, 3in

The Parshall Flume is the most widely used flume and has been the standard for flume measurements since designed in the 1930's. The main advantage of the Parshall Flume is its relatively low loss of head. The head loss is only about a fourth of that needed to operate a weir having the same crest length. This allows a wide operating range for a given size flume. The tapered approach section followed by the downward sloping floor of the throat gives the Parshall flume its ability to withstand relatively high degrees of submergence without affecting the flow rate. Another advantage of the Parshall Flume is its self-cleaning capacity.

Standard Parshall Flume sizes 1 inch through 72" throat width.
Available without discharge section resulting in short overall length for applications where submerged flow does not occur (modified Parshall Flume)
