Palmer-Bowlus Flumes

The Palmer-Bowlus flume is well know in the sanitary field, and has been used in the Los Angeles area for over 60 years. It's primary application is in pipelines, in round bottom channels or in manholes where it is often preferred because of cost and ease of installation that can minimize construction expense.

Parshall Flumes

Used in monitoring sewage, plant effluent, storm water and irrigation water the Parshall flume is still the best known and most widely used for permanent installations. It is available in throat sizes from 1 inch to 12 feet. Parshall flumes are available with numerous accessories and adaptations to match your flow and installation requirements. Made of fiberglass reinforced polyester (FRP) Plasti-Fab Parshall flumes offer optimum corrosion resistance and are the industry leader in measuring flow. For extremely severe industrial effluents they are also available in Vinyl Ester, stainless steel or other special materials as needed.

Trapezoidal Flumes

All Trapezoidal flumes exhibit similar flow characteristics, and have application advantages over other flumes and weirs.

  • The bottom is flat from entrance to exit for better head conservation.
  • Trapezoidal flumes do not require a free-fall discharge to operate correctly.
  • The staff gauge and instrument mounting brackets are located within the flume and are factory installed.
  • The natural shape of the flume mimics many earthen and concrete-lined ditches. Little or no transition is required in these situations.
