Abstract: A gas flow warning alarm device to produce an alarm indication when the gas flow rate in a pressurized gas system violates at least one predetermined limit. The alarm device includes a gas flow sensing and error signaling subassembly to generate an error signal upon sensing a violative gas flow rate, and an indicator subassembly activatable by an error signal to produce an alarm indication. The gas flow warning alarm device responds both to the depletion of a pressurized gas reservoir and to blockages and disconnections in a gas line downstream of a regulator. A method for detecting gas flow malfunctions in a pressurized gas system. A reservoir changing device to open a filled reserve reservoir of gas to a pressurized gas system upon receiving an alarm indication that pressure in a primary gas reservoir has fallen below a predetermined limit.
