Brand New BETOOLL Argon / CO2 regulator and flow meter..
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..
And this flowmeter does not use a diaphragm, so it is more reliable than the flow-gauge style regulators..
The output flow is adjustable from 10 to 60 cfh (cubic feet per hour), and is indicated by a ball which moves up and down in the flow tube..
