Flow Meters are more accurate than the flow gauge regulators. The pressure gauge which shows how much gas is left in the tank goes from 0 to 4000 psi.
The output flow is adjustable from 0- to 25 lpm, and is indicated by a ball which moves up and down in the flow tube, so this flow meter will handle MIG and TIG welding both steel and aluminum. The fitting is a CGA-580 fitting, so it fits all argon, helium, nitrogen, and argon/CO2 mixed gas tanks. This does not fit CO2 cylinders. If you want a CO2 Flowmeter see our auction for those.
A very nice thing about this Flow meter is the outlet will fit both the female 9/16" x 18 nut or the male 5/8" x 18 fitting. You can see the adapter in the picture. It comes with a standard 1/4" barbed fitting. If you have a Miller, Lincoln, or Hobart welder, the gas hose from your machine should screw right in, as they should use the 5/8" x 18 male nut.
