Pressure readings on CO2 cylinder

I just set up a CO2 system using a Dupla regulator. The pressure reading is
bar pressure, not PSI and when I first hooked it up it was at 40 bar. It
has been climbing slowly since I hooked it up yesterday and is now a little
less than 50. The gauge says the optimal pressure should be between 60 and
80.

What, if anything, should I do? Should I be worried?

Was the tank cold when you took the first reading?

Freezing. Still is, in fact. It's been well over 24 hours.

that is the key. the colder gas is more compact and isn't under as much
pressure. As the tank warms up to room temperature the pressure will
increase. Don't worry about it, it is normal.

Thanks. I figured as much, but I didn't have any idea that it would take
this long for it to warm up to room temp. It's a 20 lb tank, so I guess
I'll keep waiting...

I think recommended refilling levels of co2 cyclinders is to 50 barrs.
I do not think going to 80 barr on a refill is a good idea, atleast
with std pressurized equipment. If you had it refilled in the US this
is probably the case.

one thing to remember is that this gauge may not be very accurate.
