Smart Remote Reading NB-IOT Water Meter
Introduction:
The Smart Remote reading water meter adopts the advance NB-IOT (Internet of Things) communication technology, Through microelectronic control circuits, it converts the pulse signals of traditional mechanical meter into electrical signals, then the metering data is transmitted to background platform through NB-IOT network automatically.
Main Features:
Simple Construction:
Robust design with communication modem built in the meter.
2. Data Storage Retrievable:
With great capacity, the NB-IoT modem can store energy data at least 2 months to avoid data loss in case of network gone.
3. Remotely up-gradable:
The internal program of communication modem can be remotely upgraded, which is convenient for after-sale system maintenance.
4. Automatic reading without manual:
Remote reading of meter data through communication modem to reduce on-site labor costs.
5. Flexible Communication Selection
The communication module can be selected according to the local network mode, for example, NB-IoT, GPRS, 3G, 4G and LoRa can be selected to achieve a matching network connection.
Anti-Tamper Functions:
Meter will automatically close the valve after detection of magnetic field and open cover event.
Step Tariff:
Meters can be set Step Tariff by inputting corresponding TOKEN. Utilities can set step price on request.
Information Inquiry:
Consumer could check the data like Credit Remain, Total Purchased and Total Credit by input the short code.
Overdraft Collection:
Non- Revenue water (Overdraft) can be collected day by day or month by month.
