ABSTRACT:
A method and apparatus for determining the calorific value of a combustible gas including passing an amount of gas through a hydrocarbon detection device comprising interconnected first and second measuring cells, the first measuring cell including a catalyzing substance, wherein the first and second measuring cells provide a signal, the signal is integrated to determine a value, and the value is compared with calibrated values to determine the calorific value. In another embodiment, the Wobbe index of natural gas is determined further including determining the density of the gas and calculating the Wobbe index from the calorific value and density.
