Plasti-Fab engineered composite flumes provide optimum corrosion resistance. Available in a wide range of functional designs and custom sizes, there's a Plasti-Fab flume solution for each specific need.

Characteristics common to Plasti-Fab 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 steel flumes. Rugged Construction - Plasti-Fab flumes are molded with precise throat dimensions. Most flumes are built with minimum 2" flanges. Top spreaders are factory installed for stability. Lightweight laminated foam ribs with a large cross section limit wall and floor deflection much 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.

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.

RBC and Step Flumes

RBC and Step Flumes

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

Parshall Flumes

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.

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.

Trapezoidal Flumes

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.

H, HS and HL Flumes

H, HS and HL 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.
