Abstract
A fuel valve for regulating a flow of fuel to a combustion appliance includes a control module configured to determine fuel consumption based on a measure related to fuel flow through the fuel valve. The measure related to fuel flow through the valve may be determined using a known relationship between firing rate and the flow rate of fuel through the valve. Measurement accuracy may be enhanced by correcting for the excess air ration (also referred to as lamda).
