SUNTRONT - Model NB-IoT -Smart Water Meter

NB-IoT water meter is used for measuring water flow rate through pipe via wireless NB-IoT network upload water consumption

The whole NB-IoT meter reading system consists of ultrasonic water meter, and monitoring management software. The management center can read and monitor water meter accumulated water consumption, instantaneous water flowrate info by NB-IoT network directly.

NB-IoT water meter can configure 3 days to upload for each month, and in these three days, each day can set 2 time periods to bring device online, and the user can configure time according to the need. During online time, management center can read real-time accumulated water consumption

1. Adopt industrial level NB-IOT module, SIM card adopts industrial M2M IOT SIM card
2. Adopt lithium battery: battery lifetime is more than 8 years, and if the power is failure, the data can be saved for 30 years
3. Remotely prepaid function, support 5 tariffs 6 prices, bill calculation mode can be set as monthly, quarterly or yearly
4. Schedule task to upload and go online : the daily water consumption of current month and last month, accumulated water consumption, balance (water quantity) will be uploaded.
5. Can set two 2 time periods to bring device online: can read the meter in real time when it goes online.
6. Alarm when being attacked, low battery power, low balance, valve failure and owing
7. LCD display, it can display water consumption, signal strength, battery power, valve status, and etc.

1. The installation of water meter should meet the installation requirements of GB/T778.2
2. The caliber of water meter shall be based on the size of the pipeline and the usual used water flow is no more than common flow of the water meter; and the installation location shall be avoided insolation, flooding, freezing and pollution, and convenient for installation, removing and reading data.
3. The sands and stones and other sundries in the pipeline, such as hemp thread shall be cleaned firstly in case of water meter breakdown.
4. NB-IoT water meter should be installed horizontally (display face up).
5. Please leave enough space for repairing, and installation according to water flow direction on the pipe.
6. Please do not apply too much force when connecting the NB-IoT water meter and pipe, to avoid damaging the meter body and leakage.
7. If the water meter is installed on the inlet of the boiler, shall install check valve on the outlet of water to prevent the return current of hot water and steam from damaging the water meter.
