Oct 24, 2006 Designed for high-pressure/liquid cylinder or pipeline use, tamper-proof Gas-Saver regulator lets user remove key after appropriate flow rate is set to control process quality. Non-compensated flowmeter accurately displays gas flow rate, even when coupled regulator is adjusted to as low as 3 or 4 psi. This minimizes static pressure buildup in hose that would otherwise lead to surges, reducing weld defects and minimizing shielding gas usage.
