An electronic sensor and fill controller for use with a refillable liquid gas container is disclosed. The present invention in broadest terms comprises a valve body for the container, a shaft extending from the valve body into the container, an electronic sensor disposed on the shaft, and a controller adapted to initiate, terminate or alter an electrical signal once the sensor senses contact with the liquified gas. In a preferred embodiment, the invention comprises a float switch and fill controller for use with a refillable LG container, comprising: (a) a shaft adapted to extend into said container so as to be substantially opposed to the pull of gravity on said container; (b) a float slidably attached to the shaft, the float moveable between a first position to a second position as the liquified gas container is charged with a liquified gas; (c) a valve body adapted to be sealingly attached to the container so as to close the container, the valve body having a liquified gas passage therethrough and a valve adapted to control the flow of a liquified gas through the liquified gas passage; (d) a electronic sensor positioned so as to sense the movement of the float from the first position to a second position, the sensor comprising an electric signal generator adapted to send an electrical signal; and (e) a controller adapted to perform at least one function selected from the group consisting of: (i) initiate an electrical signal upon sensing that the float has moved to one of the first and second positions; (ii) terminate an electrical signal upon sensing that the float has moved to one of the first and second positions; and (iii) alter an electrical signal upon sensing that the float has moved to one of the first and second positions.
