Sampling aperture
diameter
The diameter of the sampling aperture results from the number of aspiration
apertures. The precise value can be found in Chapter 4.3.2 "Simplified pipeline
project planning”.
The pipe is concluded with an end cap without a bore.
Arrangement
The aspiration apertures should be arranged against the air flow.
During project planning, it is to be taken into account that the air conditioning
ducts for mounting the pipe system are often only accessible from two sides.
Example
The following illustration depicts two project planning examples of pipe systems
in air conditioning ducts.
