In the automotive industry, argon is used together with other gases such as forming gas for welding body parts, frames, etc. Argon is used to create an oxygen- and nitrogen-free environment for heat treatment processes.

Helium is used as a test gas for critical parts such as radiators or air conditioning systems.

Airbags are increasingly being inflated with a mixture of helium and argon. Nitrogen is an important safety component in airbags.

Nitrogen is used in many manufacturing processes alongside other welding gases to produce vehicle parts such as frames, silencers, etc.

The Consumption sensor VA 520 can be used in existing pipelines from DN 15 to DN 80 for Flow measurement of Argon, Helium and Nitrogen or gas mixtures of Argon and Helium.
