发明名称 Device and method for directly measuring calorific energy contained in a fuel gas
摘要 The invention concerns a device (10) for measuring calorific energy contained in a fuel gas transported in a pipe (16) comprising a gas meter (12) measuring a volume V in pressure conditions P and temperature conditions T of a gas circulating in said pipe and an apparatus (14;52;63) to determine the gas calorific power H. The invention is characterized in that said apparatus for determining calorific power measures at least one physical variable proportional to the number of molecules of the gas different constituents in a given volume and is placed as near as possible to the gas meter so as to determine the calorific power H(P,T) in similar pressure P and temperature T conditions as those wherein the gas volume V(P,T) is measured, said device then determining the calorific energy H(P,T) V(P,T) contained in the gas.
