Planning with Single-hole Monitoring

Depending on the pipe configuration, the following system parameters are used to detect a
single air sampling opening or a particular number of obstructed air sampling openings.
Planning is to be carried out according to regulations specified in Section 3.6 Standard Pipe
Planning, page 37. Additionally, the following limiting values and opening diameters must be
observed. An additional accessory (air filter, condensate separator etc.) can have an effect on
the maximum pipe length.
