1. Under normal signal conditions, the data upload rate can reach over 99%.

2. Water meter management has changed from "passive" to "active" to prevent potential losses, including freezing and leakage.

antifreeze

The temperature sensor detects the temperature of each water meter at regular intervals. When the temperature of the water meter is below 0 ℃, the controller automatically starts the heating function, and the meter stops heating when it reaches above 0 ℃. There will be temperature display in the background. In the case of extreme low temperature - with a minimum temperature of -25 ℃ at night and a maximum temperature of -10 ℃ during the day, or in the case of extreme low temperature and continuous cloudy weather for 84 hours, the water meter inside the box will not freeze.

Low temperature alarm

When the ambient temperature inside the box is below -2 ℃, the system automatically issues a low temperature alarm. Timely remind the management to take measures to prevent equipment damage due to low temperatures.

Box door open alarm

The door magnetic switch will be triggered when the box door is opened, and the controller will record the status and upload it to the cloud. After receiving it, the backend system software will display the box door alarm. Promptly remind the management to discover and handle losses caused by accidental opening or failure to close the meter box properly.

Water immersion alarm

When there is a leak in the water pipes, valves, or water meters inside the meter box, the water immersion sensor will detect the accumulated water inside the meter box and upload it to the cloud. After receiving it, the backend system will display a water accumulation alarm. Timely detect and solve internal leakage problems, reduce leakage rates, and avoid related losses.

Power outage alarm

If the central control unit detects that the solar charging device and the battery equipped in the meter box are disconnected or in a power-off state, the system will issue a power-off alarm. Ensure the normal operation of energy storage devices and respond to anti freezing needs at any time
