  • Patent number: 7171852
    Abstract: A tracking assembly and method for tracking the operation of a rotary gas meter that has a driven member includes a connecting member, a gear assembly and a mechanical counter. The connecting member is adapted to be coupled to the driven member. The gear assembly is adapted to be coupled between the connecting member and the mechanical counter. The mechanical counter is used to count a value that is directly proportional to the number of rotations of the driven member when the connecting member is coupled to the driven member. The value provided by the mechanical counter is multiplied by a conversion factor such that the associated volume of gas displaced by the gas meter can be determined.
