A system for measuring the quantity of fuel oil consumed by a furnace burner of the gun type and particularly one used in home heating. Without the need to incorporate a device such as a sensor into existing fuel supply lines or fuel storage tank, the system predicates the fact that oil burner nozzles deliver an accurately constant rate of flow. The fuel consumption of the burner may, therefore, be computed accurately by providing a meter to measure the accumulated elapsed time during which the burner is in operation and then convert this information to gallons (or other units) consumed, by multiplying the accumulated time by an appropriately chosen factor, related directly to the delivery rate of the nozzle.
