should not be used in temperatures over 90ºC (194 ºF). If your
application temperature exceeds this temperature/pressure, we
recommend using copper or stainless steel tubing, depending on the
compatibility to the measured gas or liquid (see section 2.4)

Installation of the Pipe Section
Note!!! Before starting to install the Pipe Section, please
make sure that the piping is not under pressure from flow
of liquid/gas!
The pipe section can be installed in any desired direction, vertically
or horizontally or angular and the direction arrow on the pipe section
denote the di- rection of the flow. It is very important that the pipe
section is mounted with the correct direction, as the function of the
Flow Monitor otherwise will be prevented. The piping shall be rigid
and free from vibrations and hoses connected directly into the
Monitors should be avoided as much as possible. If you have weak
piping we advise you to use the M6 mounting hole (only on GL -
series) on the backside of the pipe section, to fasten the pipe section
to a wall or a rigid bracket. The straight runs before and after the
Monitor should not be too short, in order to avoid disturbances,
which can cause the Monitor to show incorrect values. We
recommend giving at least 10 - 15 diameters up- stream and 5
diameters downstream. (Please see Fig. 1)

The reason for this procedure is to achieve a stable flow profile
inside the pipe and by doing so, get a true reading. Please be aware
of the fact that it is practically impossible to predict when the flow is
stable after disturbances in the piping, so this must serve as a
