Gases are used to avoid the spoiling of foods and beverages and to keep them fresh for a long period of time.

In this case very often special gas mixtures are used to get the desired effect (like e.g. nitrogen and carbon dioxide mixtures).

The gases which create a protective atmosphere (MAP) are brought into the food packaging under pressure by means of special machines.

The flow sensor VA 520 allows a reliable measurement and monitoring of the flow of most gases and gas combinations. The system is compatible with system diameters from ¼“ to DN 80.
