ABSTRACT:
An improved electronic measuring system which not only determines the amount of fuel oil consumed by a home, office, or factory heating system, but also detects leaks in underground fuel storage tanks, errors in oil deliveries, heating system problems such as clogged nozzles, lines, filters, etc. and declining heating system efficiencies. The measuring system consists of an electromagnetic counter, printed circuit board with electronics, transformer, and dipswitches which are located in an enclosed housing. The device calculates fuel consumption rate via a mathematical algorithm based on burner nozzle size, fuel pump pressure, and burner flame-on time. Errors in count are avoided by using the burner's photo-optic cell output, and maintaining constant power to the electronics.
