Flowmeter and Regulator Combinations

Single and Dual Stage, Stainless Steel and Brass
Barstock Regulator Flowmeter Combinations
The 3000 Series regulators are intended for primary pressure and
flow control. The regulator flowmeter combination is a hybrid of
the 3032 and 3022 series for stainless steel and the 3012 and
3002 series for brass.
