- Make sure this fits by entering your model number.
- Brand New BETOOLL Argon / CO2 / Helium regulator and flow meter.
- Flow Meters are more accurate than the flow gauge regulators.

- 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.
