Comply with the limit values of the TITANUS MICRO·SENS® for each pipe
system of the selected pipe project planning (see chapter "Project planning
limits").
TIP
Symmetry of the pipe system
The following conditions are applicable to extract consistent air samples via
all aspiration apertures:
▪ The length of the shortest branch and the length of the longest branch
must not exceed a ratio of 1:2.
▪ The number of aspiration apertures of the respective branch may not
exceed a ratio of 1:2.
▪ The aspiration apertures should be as evenly distributed as possible in
the respective branches.

Examples of symmetrical and asymmetrical U-pipe system
The previous figure shows an example of a U-pipe system with symmetrical
or asymmetrical layout and with the diameters of the aspiration apertures
calculated accordingly. The diameters of the aspiration apertures are
determined separately for each branch of the pipe system and depend on
the total number of aspiration apertures on the respective branch. The
corresponding diameters of the aspiration apertures can be found in the
tables in chapter "Diameter of the aspiration apertures".
