Strict environmental regulations and increasing competitive pressure, especially in the chemical industry, are leading to an increase in productivity and a simultaneous reduction in exhaust gas emissions. In many processes, process air is used as an oxidising agent. The oxygen content can be increased by feeding in gaseous oxygen. The addition of pure oxygen results in decisive advantages, e.g:

• Smaller quantities of gas so that smaller blowers can be used
• Less effort required for exhaust gas treatment
• Lower overall operating costs

Oxygen enrichment enables significant process intensification, which makes processes more efficient and therefore more economical.

The VA 550 Insertion type sensors for Consumption measurement / VA 570 Flow meter are the ideal consumption meters for Flow measurement and Consumption measurement of oxygen, hydrogen and carbon dioxide.

Technical gases such as oxygen, hydrogen and carbon dioxide are used in a variety of ways in syntheses in the chemical industry.

Gaseous oxygen is used in the production of hydrogen peroxide.

Oxygen can completely replace process air in oxidation processes or serve to enrich the process air.

The VA 550/VA570 flow meters for oxygen can be used to measure the exact flow rate or consumption quantity of Technical gases such as oxygen, Nitrogen, argon, carbon dioxide, hydrogen, helium, etc. The DS 400 mobile and DS 500 mobile chart recorders can be used to document test runs of test systems easily and reliably.

For stationary systems where the consumption and flow rate of Technical gases such as oxygen, nitrogen, argon, carbon dioxide, hydrogen, helium or flammable gases such as Natural gas, methane, propane etc. are to be measured, the VA 550 and VA 570 Gas meters with DVGW approval can be connected to stationary DS 400 or DS 500 Chart recorders.
