<p>An energy metering device (100) includes a volumetric flow meter or mass flow meter (102) in combination with a gas analyzer that provides telemetry regarding the constituents of a natural gas flow stream. An interpreter (112) analyzes this information and provides a real time output corresponding to the enthalpy of combustion for the gas stream. This output is used to adjust or throttle the gas flow stream for purposes of delivering the flow stream according to a preselected parameter, which is related to desired operating conditions for a combustion device including a boiler or an engine.</p> |
