COUNTER MODULE ADAPTOR ASSEMBLY FOR ROTARY GAS METERS

摘要

An apparatus for use with a backup counter module, the apparatus having: a housing having a first end for coupling the housing to a gas meter body, and a second end for coupling an electronic counter module to the housing; and the second end having an inner surface with at least two sets of backup counter module engagement features for securing an output end of a backup counter module in one of at least two backup counter module positions. The housing may be coupled to a first gas meter body with a backup counter module positioned within the housing in one of the at least two backup counter module positions. The housing may alternatively be coupled to a second gas meter body with the backup counter module positioned within the housing in another of the at least two backup counter module positions.

1. A backup counter module having an input end and an output end, the backup counter module comprising:
a frame; a driven shaft mounted to the frame and having an end for coupling to a counter drive shaft of a gas meter body, the driven shaft end located at the input end of the backup counter module; a mechanical counter mounted to the frame and coupled to the driven shaft so that rotation of the driven shaft increments a value of the mechanical counter proportionally to the rotation of the driven shaft; an output shaft connected to the driven shaft through a gear train so that rotation of the driven shaft results in a proportional rotation of the output shaft, the output shaft having a mount for receiving a magnet so that the magnet rotates in direct proportion to rotation of the output shaft, the mount located at the output end of the backup counter module; and one or more housing engagement features at the output end of the backup counter module for securing the output end of the backup counter module in one of at least two backup counter module positions within a housing.
