With co2 expanding with heat, etc isn't that going to screw up that level? Reminds me of those batteries with the life indicator on the side back 9 years ago. Don't see those that much anymore. And putting the burst disk in the tank, IMHO makes the product say, well if the disk in the valve fails, then this one won't. I understand HPA having 2 disks sometimes, but a co2 tank? And a 3K disk at that when the tanks rated for what 1800psi?
