The wireless AMR water meter(NB-IOT) 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. It can realize daily automatic data push and remote valve control valve.
Ⅱ.Features
