Determining extended gas properties

The composition of natural gas is subject to inherent fluctuations. Gas properties are of essential interest for customers of grid operators, in particular for industrial enterprises that use natural gas for their processes. 

As downstream grid operators, you receive from us the gas quality values "calorific value, standard density and CO2 mass fraction" according to the Gas Cooperation Agreement and the DVGW G 685. These values are calculated by us at the exit points of terranets bw using our gas quality reconstruction system (RECO system).

We are also happy to calculate thirteen further parameters within the scope of extended gas properties using our certified and approved RECO system. And we perform this service around the clock. On a monthly basis, we can transmit the data you require in a standard format as daily averages.
