Palmer & Bowlus flumes
It is very important for the overall measuring
accuracy to comply with the installation
instructions on the next page.
The Palmer & Bowlus flume is characterized
by its circular connection which makes it
easy to install in pipelines.
The flume is aimed at measurement in the
scale of 20 - 100 % of the nominal flow.
No simple formula can be set up for the
Palmer & Bowlus flumes; the formulas are
defined individually for every flume.
