Overview:

This water meter uses NB-IoT narrowband cellular technology ，does not require self-networking，which directly connects to the public network and each water meter works independently as a terminal. 

Features:

1.Payment Mode

Embedded with 5-level tiered water prices, support multiple payment methods such as platform prepayment, meter prepayment, and mixed charging.

2.Data Storage

With hourly, daily, monthly cycle data and dense data recording functions, including cumulative flow rate, sensor signal strength, etc. Data can be saved for a long time while power failure.

3.Intelligent Monitoring

Alert for low battery voltage, sensor abnormalities, magnetic interference, and can also set warning water volume, overdraft water volume, etc.

4.Ultra-Low Power Consumption

Adopts a low-power design, with a large-capacity battery built-in, and  battery life up to 6 years.

5.Technical Support

It can be protocol docked and interface docked to meet the needs of different platforms.

6.OTA Remote Upgrade

All devices support remote online upgrade without the need for replacement, disassembly, or close contact with the meter.

7.Convenient Payment

It supports mobile payments such as WeChat, Alipay, Mini Programs, etc., to check usage, balance, payment information, etc.
