High-tech, accuracy and reliability 

Our service in the field of gas measurement

Every hour, many millions of cubic metres of natural gas flow through the networks of the gas network operators. For billing, balancing and control purposes, the transported amount of energy is measured wherever gas is fed in or withdrawn. Do you need support as a metering point operator, immediate help with operational problems or do you want to realise special metering projects?

With many decades of experience in gas measurement technology, we are your competent partner. We offer you the entire range of tasks in large-scale gas measurement, from planning to operation, including maintenance and servicing. Our outstanding technical know-how as well as state-of-the-art measurement technology is even successfully applied to over 1,000 OGE measurement systems.

The calibration of certification and test gases

Depending on the origin of the gas supplied, the gas quality and thus the calorific value may vary. The measurement of the gas quality is usually carried out at representative points in pipeline networks with calibrated process gas chromatographs. The accuracy of the results is significantly influenced by the quality of the calibration gas used. OGE analyses and prepares preliminary test certificates of calibration gases as a state-approved testing laboratory.

Our offer in detail

  • High-precision analysis and certification of calorific value, standard density and mole proportions of calibration gas mixtures
  • Pre-testing of calibration gases for process gas chromatographs and calorific value measuring instruments
  • Pre-testing of calibration gases with proportions of hydrogen in natural gas
  • Certificate as a state-approved testing laboratory
  • Express certification on request

Mobile measuring and analysis systems

In case of failures and malfunctions of measuring devices, the use of mobile and flexible measuring and analysis systems from OGE is suitable. These can be used at short notice at almost any location and provide analysis results of the highest quality and reliability.
