Function
3.4 Leakage rate Q
L
If no leakage rate is specified, we recommend the max.
possible test period/measurement time is set.
It is possible to check a specific leakage rate Q
L
using
the TC. Within the scope of the European Union, the
maximum leakage rate Q
L
is 0.1% of the maximum flow
rate Q
(n) max.

If a small leakage rate Q
L
is to be detected, a long test
period/measurement time must be set.
