Specification of Smart Water Meter
GPRS water meter
GPRS/NB-IoT water meter is a new remote water meter based on GPRS network or NB-IoT network. NB-IoT water meter adopts the special network communication, the data communication is safe and reliable.Structural design of electromechanical separation, easy installation on site and convenient maintenance, it can be installed wherever there is a cell phone signal.
1, Product Features:
1) Water meter data is transmitted through GPRS & NB-IoT private network, safe and reliable;
2) Water meter adopts the electromechanical separation structure design, the early stage installation construction is simple, the later stage maintenance & the replacement is convenient;
3) The design of double Hall sensor can realize the forward and backward metering of water meter, ensure the complete synchronization of electromechanical, and there is no accumulative error.
4) Built - in large - capacity lithium battery , the battery life is over 6 years ;
5) Water meter pre-storage 6 years module communication costs, do not need to worry about arrearage downtime
6) Monitor magnetic interference, low voltage battery, upload abnormal alarm to meter reading platform, monitor in real time
