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 Standard pipe planning,
page 32 . 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.
