Palmer & Bowlus flumes
Note!
General
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.
For the Palmer & Bowlus flumes with the
dimensions as listed in the table below, the
flow formulas are defined and incorporated
in the flow converter and is chosen in the
menu “Programming of flow calculation”.

Installation instructions
Mounting of the flume
Mounting of the
ultrasonic sensor
1: The flume should be mounted in-line in the pipe without contractions both upstream and
downstream.
2: The flume section should be mounted in absolute level .
3: To obtain a precise measurement, it is important that both the upstream and the down-
stream pipe slopes downwards equally to ensure the water never accumulates in the
measuring section of the flume.
4: Position the flume correctly in relation to the flow direction. Observe the flow direction as
indicated with an arrow on the top edge of the flume.
1: It should be mounted firmly.
2: It should be mounted absolutely vertical.

3: The ultrasonic sensor should be mounted so the ultrasonic signal can pass without any
obstructions from pipes, cables and other installations.
