Applications / Flow Measurement / Consumption meter for oxygen, hydrogen, carbon dioxide

VA 550 insertion sensor / VA 570 flow meter with ATEX approval and special cleaning (free from oil and grease) for flow and consumption measurement of oxygen ( O2), hydrogen (H2), carbon dioxide (CO2)

Especially in the chemical industry strict environmental requirements and continuously increasing competitive pressure lead to an increase of productivity and at the same time a decrease of the exhaust emissions.

In many applications process-air is used as an oxidant. The oxygen content can be increased by feeding gaseous oxygen into the application.

Adding pure oxygen leads to the following advantages: 

  • smaller gas amounts and therefore smaller blowers
  • less expenditure on emission treatment
  • lower total operating costs

Oxygen enrichments allow a significant process intensification which makes the processes more efficient and more economic.

The VA 550 and VA 570 flow meters are the ideal instruments for consumption and flow measurement of oxygen, hydrogen and carbon dioxide.

For syntheses in the chemical industry technical gases like oxygen, hydrogen and carbon dioxide are used in various ways.

Gaseous oxygen is used during production of hydrogen peroxide.

Oxygen can completely replace process air in oxidation processes and it can be used for enrichment of process-air.

With the flow meters VA 550/VA570 the exact flow amount or consumption of technical gases like oxygen, nitrogen, argon, carbon dioxide, hydrogen, helium can be measured. By making use of the portable chart recorders DS 400 and DS 500 trial runs of test plants can be documented easily and reliably.

At plants where the consumption and the flow of technical gases like oxygen, nitrogen, argon, carbon dioxide, hydrogen and helium and/ or combustible  gases like natural gas, methane, propane etc. should be measured on a continuous base the gas flow meters VA 550 and VA 570 with DVGW approval can be connected to the stationary chart recorders DS 400 and DS 500. 

We recommend:

Flow Meter with ATEX Approval - VA550

VA 550 - Flow meter for heavy duty industrial applications

Our extra robust flow meter is available as ATEX-version for application in explosive areas

Flow Meter with Measuring Section - VA 570

VA 570 - Flow meter with integrated measuring section

The measuring sections are available in flanged version or with R resp. NPT thread.
