Miller-Smith Flowmeter 2230 Single Stage

The Miller-Smith Flowmeter 2230 is a single-stage gas regulator built for welding applications. It connects to a cylinder with a 1/4 in MNPT inlet and delivers gas through a 5/8 in -18 RH internal outlet. The brass body and 304 stainless steel components provide durability for general-purpose use.

Suited for argon CO2 helium shielding gas

This regulator suits welders who need a fixed 50 psi delivery pressure for argon, carbon dioxide or helium shielding gas. The self-centering ball and shatter-resistant polycarbonate tube give clear flow indication. It is not for operators who require adjustable outlet pressure or multi-stage regulation for precise pressure control.

Fixed 50 psi delivery from 50 psi inlet

The unit delivers a constant 50 psi outlet pressure from a maximum 50 psi inlet supply. This provides steady flow for typical MIG and TIG welding tasks with the listed gases. Headroom is limited because inlet and outlet pressures are equal so it cannot boost pressure or compensate for dropping cylinder pressure.

Questions about this item

What gas supply do I need already to use the 2230 flowmeter?

It connects to a cylinder regulator supply for Argon, Carbon Dioxide or Helium shielding gas.

Will the 1/4 in MNPT inlet and 5/8 in -18 RH internal outlet fit my existing hoses?

The inlet threads into a 1/4 in MNPT regulator port; the outlet accepts a standard 5/8 in -18 RH internal fitting used on many MIG and TIG gun hoses.

How do I know the 2230 is regulating at 50 psi after installation?

The self-centering ball inside the shatter-resistant polycarbonate tube rises to show flow; verify the delivery pressure reads 50 psi on your system gauge.
