Patent ID: 8281823

Claim:
A refueling apparatus for use in refilling a container with a fluid from a fluid source, said refueling apparatus comprising: a fluid flow control valve module; a fluid level sensor module; and a testing module; said fluid flow control valve module having a fluid passage there-through for connection with said fluid source, said fluid flow control valve module having a shutoff valve, wherein said fluid is able to travel from said fluid source through said fluid flow control valve module and into said container when said shutoff valve is open, and wherein when said shutoff valve is closed said fluid is prevented from flowing through said fluid flow control valve module, wherein said fluid level sensor module is able to control the opening and closing of said shutoff valve; said fluid level sensor module having a sensor configured sensing the fluid level in said container, said fluid level sensor module configured for closing said fluid flow control valve module upon said sensor sensing that said fluid level is higher than a predetermined level in said container and opening said fluid flow control valve module upon said sensor sensing that said fluid level is lower than a predetermined level in said container; and said testing module for simulating a predetermined fill level in said container, said testing module comprising a valve member blocking said fluid passage from a supply line through an inlet port and out an outlet port thereby allowing the function of the fluid level sensor module to be tested.
