I have a dennerle regulator that I use with a 2kg fire extigisher. When I attach a new FE and fire it the top guage goes to around 60 psi. I then set the opperating pressure to just over 1 bar.
How do I know when to replace the CO2? I assume the pressure will drop in one of the 2 guages. Which one and how long after this drop before the FE dies?
