Abstract

The fuel gas or a substream of the fuel gas is passed through a volumetric flowmeter and the volumetric gas flow is measured. In addition, the pressure, temperature and the proportion of at least one inert gas as well as the density and the dielectric constant are measured under reference conditions. The amount of heat supplied to gas consumption devices can be determined from these six parameters reliably without complicated technology.
