Abstract:
The present invention provides a method and apparatus for controlling a level in a receptacle capable of storing a fluid. The apparatus includes a first valve governing ingress of the fluid to the receptacle, a second valve governing egress of fluid from the receptacle, wherein the second valve is positioned below the first valve. The apparatus also includes a first switch deployed between the first valve and the second valve, wherein the first switch is capable of providing a first signal indicative of fluid at the first switch and a second switch deployed between the first switch and the second valve, wherein the second switch is capable of providing a second signal indicative of an absence of fluid at the second switch. The apparatus also includes a controller capable of controlling a fluid level in the receptacle by opening and closing the first and second valves responsive to the first and second signals.
