Palmer & Bowlus flumes

Palmer & Bowlus flume

Palmer & Bowlus flumes are designed for installation in partly full pipes.

• Connection to standard pipelines
• Many applications in wastewater for measuring continuous flow and storm flow
• Flumes are often mounted in wells, where only a few adjustments for installation are made
• The simple form keeps the flume clean.
