Montana Flumes were specifically designed for applications where flow free-falls out of the end of the flume.
In fact, the Montana Flume is a modification of the Parshall Flume where the throat and discharge sections are removed.
Montana flumes use the same discharge equations as Parshall flumes and are available with many of the same accessories as the Parshall flume (other than the outlet end adapter).
Montana Flumes require less room to install and cost less than full length Parshall flumes.
Note: With the throat and discharge sections removed, Montana flumes loose resistance to the effects of submergence. Montana flumes should only be used where free-spilling discharge is present under all flow conditions.
