ABSTRACT:
A process and apparatus for the combustion-less measurement and/or regulation of the feeding of quantities of heat to gas combustion devices, particularly natural-gas combustion devices. A fuel gas or a partial stream of the fuel gas is fed through a fuel gas line containing at least one flow resistor which produces a laminar flow and a pressure drop. The gas volume flow and/or the pressure drop over at least one flow resistor is measured by a volume flow metering device and a difference pressure regulator, respectively, the pressure drops and/or volume flows which are not measured being maintained constant. A device compensates for the influence of temperature on the system is compensated. The measured value(s) in accordance with the formula described in the specification
