Abstract

An automated meter reader module can be operably connected to an existing utility meter to provide an endpoint for use in an automated meter reader system. The automated meter reader module can utilize an index attachment drive mechanism to electronically and mechanically monitor consumption of a utility such as water, gas, or electricity. The index attachment of the existing utility meter is attached so that it does not physically impede reception or transmission of radio frequency communications by a patch antenna integrated into a printed circuit board located inside the automated meter reader module. A gasket around the edge of the housing sealingly interfaces with the existing utility meter and a multi-faced cover that allows the registered dials located on the index attached to be viewed from a plurality of vantage points.
