Automatic meter reading(AMR) system is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This system based on mobile communication technologies, and uses WLINK DTU as remote data transmission unit to transmit data real-time and reliably to data server center. The system saves utility providers the expense of periodic trips to each physical location to read a meter. Furthermore, the application is also suitable for water and power meter reading application.
