Regulator flow rates
When a manufacturer quotes a flow rate for a regulator in liters per minute, does it mean surface liters or actual liters? As in, is the amount that it can supply based on the mass of the gas, so the volume halves when the pressure doubles, or is it the actual volume, so it can always deliver x liters of gas, no matter what the depth?
Cheers in advance

BS EN 250:2000
BS EN 250:2000 is where you can get a copy but it'll cost you £64
I personally thought it had to deal with density which is why you can breathe He mixes no worries whatever depth, but once you dive air at deep depths, you need something that delivers massive amounts of gas (like Poseidons!)

In that case, it would suggest that it is to do with the mass of gas rather than volume, so... a Poseidon cyklon has a quoted flow rate of 1250 liters per minute, which means, presuming that the quoted flow rate is when on the surface, that it can deliver approximately 1.5 kg of gas per minute
I think...
Digger, fair point.
James, I (as in my company) have a subscription to BSOL (British Standard Online), and I have just downloaded BSEN 250:2000
PM me your email and I will email it over, it's a 20 page PDF, about 1.2mb. You can then go through it, and report back to all of us with your findings. Fair??
Obviously, our subscription is fairly tight on who is allowed stuff, I thereby grant you temporary use of my personal copy. This might be outside the user agreement, however, so I might have to request my copy back at some point
