Parshall Flume

Features
  • Sturdy Reinforced Fiberglass Construction
  • Sizes from 3"up to 36"
  • Stilling Well Connection Available
The Parshall flume is one of a large class of open channel primary elements known as critical flow venturi flumes. A distinguishing characteristic of the Parshall flume is the downward sloping invert of the throat. This feature gives the Parshall flume its ability to operate at higher ratios of downstream to upstream head than any other such device.

The Parshall flume manufactured by Eastech Flow Controls is a monolithic fiberglass reinforced polyester structure to assure maximum strength and accuracy of dimension while minimizing installation time. A staff gauge with 1/4" minor divisions in inches is standard. A 2" NPT stilling well connection is available as an option.

The Parshall 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.
