Abstract
A refrigerant recovery system that includes a refrigerant storage container, means for withdrawing refrigerant from a refrigeration system to be serviced and feeding such refrigerant to the container for storage, and a scale supporting the container for sensing impending overfill of the container. The scale includes a beam horizontally rigidly cantilevered from a base. A switch is positioned adjacent to the cantilever-remote end of the beam, and is responsive to deflection of the beam to indicate impending overfill of the container and prevent or terminate operation of the refrigerant recovery system.
