Abstract
A home site fuel monitor device in conjunction with a remote central site system to provide accurate fuel usage data used in planning fuel deliveries. The fuel monitor device is an internet based, compact, and low cost home heating site monitor device that is easily installed in the home heating site without modification to the home site's heating system. The monitor device includes a microprocessor which measures heating system run times using real time clock values. The microprocessor computes heating system fuel usage and the rate of fuel usage using heating system run times and heating burner parameters down loaded from the remote central site system. The monitor device continuously adjusts or recalibrates the rate of fuel usage defined as a burn coefficient value to coincide with the latest delivery information received from the central site system which results in increased accuracy over time.
