There is increasing interest in producing biogas from different types of biomass at a number

of smaller upgrading plants in Denmark. Some of this upgraded biogas will be delivered to the natural gas distribution grid, which give us the need to calculate/measure the calorific value, and in some cases also wobbe index, density and gas composition in smaller districts than today.

This Framework agreement is tendered in two sub agreements. One agreement for Calorific value measurement instruments and one for Gas Chromatograph instruments. It not demanded to bid at both sub agreement.
