Nowadays customer-side natural gas measurements are only focused on gas volume, while prices are increasing and the market becomes more open. Because of the efficient cost accounting, large customers get interested in measurements corrected by real calorific value. For determining the real energy flow, continuous measurement of gas consistency needed. But online gas chromatography is too expensive for even large consumers. However the information exists at provider-side databases and can be used for calorific value and energy flow computing at different customer-side locations. The aim of the research and development project was to give a cost-effective solution to these requirements. At the first we give a short theoretical overview of gas-flow measurements in cost-accounting and show the related standards. After that we define a realizable computing method, and deal with the structure and operation of the new measurement system.
