Function of NB-IOT water meter:

1.The LCD display screen displays the current signal value,balance,water consumption,remaining water quantity and other information

2.Remote reading and remote valve control

3.Early warning system:battery undervoltage and abnormal metering alarm

4.Step water price can be set according to user category and usage.

5.Battery:more than 6 years of use

6.Support internal/external antenna,stable and reliable signal.

7.High sampling accuracy

8.Reed fault detection:When a samplingreed fails,the water meter will display the reed failure,and the water meter can stillmeasure accurately.

9.Data upload frequency can be set,periodic uploads can be uploaded at intervals of minutes,hours and days.

10.The battery can be replaced directly without opening the water meter

11.The system adopts BS architecture:the browser can log in,and both PC and mobile phone can support it.

12.NB Internet of things remote water meter supports two modes:fixed time point upload and periodic upload to meet the use needs of different users.

13.Fixed time point upload supports four methods:month,week,day and hour(which days of the month,which days of the week,which hours of the day,and which minutes of the hour)
