Principle of automatic meter reading:

1. The data concentrator stores data at a fixed time (usually set to 00:00:00). At this time point, the data concentrator automatically freezes, reads, and saves the meter status data such as the cumulative reading, valve status, and battery voltage of the water meter

2. The system software reads the data regularly, reads the frozen data stored in the data concentrator through the secondary network (Ethernet or GPRS), and saves it to the database of the upstream server. Finally, it is analyzed by the software and displayed in the application.

Advantages:

1. Online monitoring of water volume data and water meter status.

2. Built-in valves can be used to achieve remote control functions.

3. No wiring required, easy installation, and not susceptible to lightning strikes

4. Automatic networking and automatic meter reading, stable data transmission, and failure of a single node does not affect the reading of water meter data in the entire meter reading network.

5. Easy debugging
