To protect flumes in above ground applications, Openchannelflow has developed a range of Fiberglass Enclosures that factory integrate small flow measuring flumes. The turnkey design allows the unit to be dropped in place and requires little in the way of site preparation.
Enclosure integration:
- Safeguards the installation - restricting access to the flume and flow meter sensor
- Reduces the likelihood that the flow meter sensor is accidentally moved
- Provides a clean, neat, and professional installation appearance
- Provides chain-of-custody for the meter and its measurements
Each fiberglass enclosure comes standard with: molded-in / U.V. protected color (white is standard but other colors are available), self-opening dual gas struts, stainless steel hinges, and a stainless steel pad lockable hasp.

Flumes available for integration include:
- Cutthroat
- 18-inch L
- HS / H
- HS 0.4’, 0.6’, 0.8’
- H 0.5’, 0.75’
- Palmer-Bowlus
- 4”, 6”, 8”, 10”, 12”
- Parshall
- 1", 2", 3"
- Trapezoidal
- Small, Large, and Extra Large

A range of accessories are available to complete the installation, including:
- Flow meter / power / sampling couplings
- Enclosure insulation
- Fiberglass drain surrounds (to allow any overspill to drain back into the flume)
- Flow meter brackets
- Optional stainless steel gas struts
- A range of molded-in gel coat colors (white standard)
- Nested (dual range) flumes
