Prefabricated flumes provide measurement of flow in open systems.
Palmer-Bowlus Flumes Features:
- Trapezoidal throat design ensures high velocity at critical flow levels
- Minimal flow restriction, low energy loss and better measurement accuracies at both low flow and peak capacity
- Smooth gel coated surfaces minimize friction and prevent solids build-up
- One-piece molded construction makes installation quick, easy and cost effective
- Components are made with corrosion resistant materials
- Maintenance free, accurate and economical
- Made of fiberglass-reinforced polyester resins laid up over white isophthallic gel-coat
- Rigid 1-piece construction and are especially well suited for measuring liquids containing solids
- Smooth surface and internal flow lines help reduce measuring errors that occur with the accumulation of debris
- Embedded staff gauge with calibration units in 0.1’, 0.02’ & ¼’’ increments
- Attached stilling wells in 12’’, 10’’, 8’’ and 6’’ I.D. can be supplied
- Shuttle® Ultrasonic Level Meter with support bracket for Shuttle® Level Transmitter
- 2 ½’’ wide standard end flanges in fiber glass
Cutthroat Flume was designed for flat gradient channels.
Cutthroat Flume Features :
- The straight through bottom (for silt and debris passage)
- Simplicity of form
- Scalability to intermediate sizes
- Constant dimensional configuration
- Able to operate under free flow conditions with submergence ratios up to 79-88% (depending upon the flume size)
- Ultrasonic mounting brackets
- Bubble tubes
- Sample tubes
- Submerged probe cavities
- Stilling wells (detached)
- Staff gauges
- Removable probe holders
- Inlet and outlet end adapters
- Pipe stubs
- Flanged end connections
- Fiberglass grating
- Riser boxes
- Multi-piece construction
- Chemically resistant gel coat
H-Type Flume was designed for the study of agricultural runoff, but are also ideally suited for monitoring storm water run-off and industrial flow monitoring.
H-Type Flume Features:
- available in HS, H, and HL styles, are sized by the depth of the flume and the geometry of the discharge face
- differ from other flumes, as they are more V-notch weirs than flume based on their exit geometry
- are more properly termed open channel flow nozzles, but are listed as flumes because of historical precedent.
Options/Extras:
- Ultrasonic mounting brackets
- Bubble tubes
- Sample tubes
- Submerged probe cavities
- Stilling wells (attached and detached)
- Staff gauges
- Removable pH probe holders
- Approach sections
- Inlet bulkheads
- Inlet PVC pipe stubs
- Flanged inlet connection
- Flow straighteners
- Fiberglass grating
- Multi-piece construction
- Chemically resistant gel coat
RBC flumes are small, portable long throated flumes designed specifically for use in small earthen channels and furrows.
RBC Flumes Features:
- The ability to accurately measure (+/-2%) very low flows
- Simple construction
- Trapezoidal cross-section (conforms to natural channels)
- Portability
- The ability to accurately measure (+/-2%) very low flows
- Simple construction

- Ability to operate under higher degrees of submergence than Parshall flumes
- Trapezoidal cross-section (conforms to natural channels and conveys large flows while providing accuracy for low flows)
- Ultrasonic mounting brackets
- Bubble tubes
- Sample tubes
- Submerged probe cavities
- Stilling wells (detached)
- Staff gauges
- Removable probe holders
- Inlet and outlet end adapters
- Pipe stubs
- Flanged end connections
- Fiberglass grating
- Riser boxes
- Multi-piece construction
- Chemically resistant gel coat
