More and more industrial processes require nitrogen. Up to now in most cases nitrogen is supplied by ”gas suppliers” in bottles, cylinders or in tanker trucks.

In order to save production costs and to be independent from gas suppliers own nitrogen generators are used for nitrogen production. 

The technology is based on modern membrane technology in which compressed air is divided into two gas streams – one with nitrogen and one with oxygen.

The flow meter VA 520 precisely measures nitrogen, compressed air and oxygen.
