Corrosion Resistant Flumes

Made of fiberglass reinforced plastic (FRP), Plasti-Fab Flumes provide optimum corrosion resistance. Available in a wide range of functional designs and custom sizes, there's a Plasti-Fab flume for your specific need. For extremely severe effluents, they're also available in Vinyl Ester, stainless steel, or other special materials as required. Our representatives and engineering staff can assist you in identifying the perfect flume for your need.

Characteristics common to all flumes:

Accurate, Economical, Long Lasting - Fiberglass flumes are more rugged and cost less than stainless steel flumes, and they are more durable than concrete or galvanized flumes.

Rugged Construction - Most Plasti-Fab flumes are built with minimum 2" end and top flanges. Top spreaders are factory installed. Lightweight laminated foam ribs with a large cross section limit wall and floor deflection better than embedded angles.

Smooth White Gelcoat Surfaces - minimize buildup of silt and organic debris, aid in reading the gage and instrument calibration, and make cleaning easier.

Easy Installation - Plasti-Fab flumes are heavily ribbed and braced for better dimensional stability and are equally effective as free-standing installations or as liners in concrete.

Types of Flumes

Plasti-Fab H Flumes

H Flumes

H-flumes measure effluent, sewage, or stormwater that have a very wide range of flow that otherwise would be difficult or impossible to measure in other types of flumes.

Plasti-Fab Trapezoidal Flume

Trapezoidal Flumes

Developed for irrigation, trapezoidal flumes have proven their effectiveness by the Soil Conservation Service and Department of Agriculture - both to monitor flows in furrows and in sloping irrigation ditches. Now they are increasingly popular for applications where low-flow measurement is required.

Plasti-Fab Palmer-Bowlus Flumes

Palmer-Bowlus Flumes

Known in the sanitary field where it is widely used for measuring flows in manholes, temporary installations or pipelines.

Plasti-Fab Parshall Flume

Parshall Flumes

The most widely known flume and still the most widely used for permanent installations. Used in monitoring sewage, plant effluent and irrigation water. Available in sizes 1 inch through 12 foot.

RBC and Step Flumes

RBC and Step Flume comprise a group of long-throated flumes that are increasingly being used for agricultural research, water shed management, runoff studies and water resource allocation.

Plasti-Fab Cutthroat Flumes

Cutthroat Flumes

Similar to the Parshall flume except that the bottom is at the same elevation as the channel invert throughout the length of the flume.
