Palmer Bowlus Flumes for Flow Measuerment
Named after its inventors, Harold Palmer and Fred Bowlus, the Palmer Bowlus flume has three installation options and is virtually maintenance free. Since the 1930s, Palmer Bowlus flumes have served as a simple and effective wastewater flow-measuring device. The flume is essentially a restriction in the channel and is sized according to the width of the flume. This is typically, but not always, the width of the pipe the flume is connected to.
Palmer Bowlus Flume Sizes & Options
TRACOM understands each wastewater management system is different, and it is our goal to help your system run smoothly. To meet your flow measurement needs, our Palmer Bowlus flumes are available in three different sizes:
- 4D+1 inch Permanent Style
- 2D+1 inch Portable Style
- Insert Style
4D+1 inch Permanent Flume Style
- 2” top and end flanges
- Integral approach section
- Point of measurement inside of flume
2D+1 inch Portable Flume Style
- 2” top and end flanges
- Shorter lay length than 4D+1” style
- Point of measurement upstream (outside) of flume
2D+1 inch portable flumes cannot be provided with bubble or sample tubes, submerged probe or Drexelbrook cavities or staff gauges. They are, however available with outlet bulkhead to connect to existing pipe.
Insert Flume Style
- 2D+1” length
- No top or end flanges
- No support ribs
- Intended to install into the lower half of an existing pipe
- Point of measurement upstream (outside) of flume
Like the 2D+1 inch style, insert flumes are also not available with bubble tubes, submerged probe or Drexelbrook cavities, or staff gauges. They are different from 2D+1 inch flumes in how they are not available with inlet or outlet bulkheads.
Choosing the Right Flume For You
Each Palmer Bowlus style flume has its advantages and disadvantages and works best in certain fields. Which style flume is best for your project?
- 4D+1″ Style Flumes work best in new construction sites due to its integral approach section
- 2D+1″ Style Flumes work best in retrofit constructions where space is a concern
- Insert Style Flumes work best in existing pipes because they do not have inlet or outlet flanges
