Accura Flo Application Notes
A common misconception about metering flumes is that one type of flume is more accurate than another. The differences between different types of flumes and different sizes of flumes of the same type, are really differences in resolution not accuracy.

Palmer Bowlus Insert Installation Requirements
Palmer Bowlus flumes are designed for use in round pipes flowing partly full and at low velocities. Typical applications are in sewer lines and storm drains. The insert style is intended for use in existing manhole inverts.

Flume Specification Standard Construction - Palmer Bowlus In Channel Liner installation requirements
Palmer Bowlus flumes are designed for use in round pipes flowing partly full and at low velocities. Typical applications are in sewer lines and storm drains. The flume size should be the same as the pipe diameter.

Flume Specification Standard Construction - Parshall Flumes Installation Requirements
The Parshall flume is intended for use in open channels such as irrigation ditches. Use extreme care when adapting Parshall flumes for use with round pipes. The flume's crest is usually set at an elevation higher that the floor of the upstream channel.

Flume Specification Standard Construction - Trapezoidal Flumes Installation Requirements
The Trapezoidal flume is intended for use in open channels such as irrigation ditches. Use extreme care when adapting Trapezoidal flumes for use with round pipes.

Flume Specifications - Standard Construction - H Flume Installation Requirements
H flumes are primarily designed for measuring flows that vary widely such as seasonal runoffs and overflow from dams. The recommended approach channel length is five times the height of the flume.
MS Word

Flume Specifications - Standard Construction - Low Flow Insert Installation Requirements
Low Flow flumes are designed for use in round pipes flowing partly full and at low velocities. Typical applications are in sewer lines and storm drains where the expected flows are below the ideal flow range for standard Palmer Bowlus flumes. The insert style is intended for use in existing manhole inverts.
