Parshall flume
For open channel flow measurements in water and waste water applications (Q/h-relationship)
The Parshall flume is recommended for those applications in which moderate concentrations of sand, grit or other heavy solids exist and fluid velocities entering the flume are subcritical. The flume operates with a small energy loss or change in channel grade, about one-fourth that of weirs having the same crest length.
The flume is ideally suited for fluid measurement in irrigation channels or sewers.
