A self-contained automated meter reader system for monitoring a plurality of channels for gas, electricity and water utilities, has additional channels dedicated to normally closed alarm signals for monitoring the integrity of the system. The system is installed at the site of a standard utility meter and is configured for monitoring and operation by a user via keyword command programming on a data terminal or personal computer. Externally entered programming communicates with a compiler in the automated meter reader unit. Pulse data is accepted from digital meter reader devices for gas and water systems and a photoelectric sensor reads the watt-hour electricity usage. Utility office communication is via telephone modem link to a computer and a lap-top computer for field setup and systems analysis. Computing electronics hardware is within the watt-hour meter housing and interfaces with utility service meters, DC power supply and telephone service through a connector on a weatherproof polycarbonate meter enclosure on a utility electric service box.
