GPRS Wireless Water Meter
INTRODUCTION
The wireless AMR water meter(GPRS) using of advanced wireless transmission technology, it transforms metered information of conventional mechanical water meter into electrical signal have it stored by micro-electronics control circuit. It is able to automatically read the metering data via wireless remote network and is also able to transfer the data to the back-office system (data center) after reading the meters.
