Are there any Double stage regulators available for argonco2 mix gas cylinder?
If yes then the manufacturers name and E-mail address?
What Outlet pressure in terms of bar to be kept on the gauge to get 20 liters per minute gas pressure at nozzle end.
Is there any Buzzer available which can be electricaly connected to the pressure gauge which automatically gives signal when inlet pressure drops below 2.5 BAR.

The Concoa 9400 series regulators are 2 stage, they vary the pressure to regulate flow. Having said that I use them but don't know what pressure they operate at. I don't see any reason that a pressure swich that closes on lowering pressure could not be hooked to a power supply and buzzer, but I don't know if anybody offers a ready made device.

If you look up amron on the net which is a diving equip company they offer a low air alarm that should work .
