3.7 Commissioning
CAUTION!
The pressure upstream of the quantometer may be increased only
slightly.
Commissioning:
Slowly fill the system until the operating pressure is reached.
The pressure rise must not exceed 350 mbar/s.
A bypass line should be used for filling (recommendation: 12
mm pipe diameter).
Do not exceed the measuring range of the gas meter even
briefly.
A tightness test must then be carried out.
