Mechanical water meter with AMR capabilities is currently widely used in many cities of India. This legacy system is inaccurate and inefficient as manual data readings is involved in it thus making it labor intensive. In this paper we present a low cost, accurate and reliable solution for reading water meter by building a custom read out device with LoRa transreceiver for communication in the existing system. LoRa RF platform is a two-way wireless IOT based solution that balances M2M (machine to machine) cellular infrastructure and provides a low-cost technique to connect battery operated devices to network infrastructure. To be well-suited with the conventional water meter, this system is mounted over the body of existing meter. A refinement key is based on sensors, microcontroller, LCD display, EEPROM and long range (LoRa) transreceiver. The water meter data is established at the billing system by hand-held device comprising LoRa Transreceiver module. The wished-for system is cost effective and gives automated water meter reading at high accuracy.
