Argon is used for welding applications and in the manufacture of lamps or lasers. In heat treatment processes, it can be used as an inert gas to create a nitrogen and oxygen-free environment.

Nitrogen is immensely important in the aerospace industry and is used in many production processes such as wind tunnels or heat treatment furnaces.

Nitrogen is used as a cutting gas in laser welding.

Helium is used in many areas, from production to flying.

Helium is used to purge hydrogen systems.

The VA 520 Flow meter with measuring section for Flow and Consumption measurement of Nitrogen, Argon and Helium is available with pipe sizes from 1/8 inch to 3 inch.
