About Flowmeters and Totalizers
Flowmeters measure the rate of flow for a liquid or a gas. Totalizers measure the cumulative flow volume. Flowmeter/totalizers display both the flow rate and the cumulative flow volume.

Easy-Read Tank-Mount Pressure-Regulating Valves with Flowmeter for Inert Gas
Male Inlet × Female Outlet With One Flowmeter
Female Inlet × Female Outlet With One Flowmeter
Male Inlet × Female Outlet With Two Flowmeters
Female Inlet × Male Outlet With One Flowmeter
Flowmeters let you see the gas flow rate from a distance. These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. They have a gauge for monitoring inlet pressure from the tank.
Single-stage valves reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank. They’re best for applications where a constant outlet pressure isn’t critical.
Two-stage valves progressively reduce pressure over two steps for more consistent outlet pressure at all times. They’re often used in applications that require a constant outlet pressure regardless of the tank level.
Valves with one flowmeter are for one piece of equipment on a tank. The flowmeter has a single scale.
Valve with two flowmeters lets you simultaneously run two pieces of equipment from one tank. Both flowmeters have a dual scale.
Adapters (sold separately) change 5/8"-18 outlets to 9/16"-18 male connections, and vice versa.

Tank-Mount Pressure-Regulating Valves with Flowmeter for Inert Gas
- For Use With: See Table
- Temperature Range: -20° to 120° F
Commonly used in TIG welding where gas flow/coverage is a concern, these valves measure the gas flow rate in addition to regulating pressure. They automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Valves have a gauge to monitor the outlet flow rate and a second gauge to monitor inlet pressure from the tank. They are single stage and reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank.

Flowmeters for Oxygen
Calibrated, cleaned, and bagged for oxygen service, these flowmeters are commonly used for welding. They install directly in your line. All have a flow-control knob that lets you open and close the valve at the inlet to adjust the flow rate within the range.

Flowmeters for Inert Gas
The correlated scale and conversion charts let you use the same flowmeter to measure the flow rate of nitrogen, oxygen, argon, and helium. These flowmeters have fittings on the back for installation in your instrument panel. The flow-control knob lets you open and close the valve at the inlet to adjust the flow rate within the range.
