A new, radio-based gas automatic meter-reading (AMR) system has been developed that offers the promise of greater AMR deployment. The system, jointly developed by engineers from Tokyo Gas Co., Ltd., Osaka Gas Co., Ltd., and Taho Gas Co., Ltd., replaces wiring between the meter and telephone line with radio communication. Most conventional AMR systems use telephone lines, and require wiring to connect the telephone line and the meter. They are difficult or impossible to deploy when there is a considerable distance between the telephone line and gas meter, or where there are physical obstacles that hinder wiring, such as walls in apartment buildings. By replacing wiring with radio communication, the new system eliminates or reduces these obstacles. Field tests have confirmed the successful practical application of the radio-controlled AMR system, using a special low-power radio. Of particular importance is the realization of almost real-time, two-way communication, a feature not found in most other radiocontrolled systems.
