TECHNICAL INDEX

Adopting ultra-low power main control CPU and electronic devices, proprietary technology, most of the time working in a low-power state, ensuring that the battery life in the meter can reach more than 6 years.

The controller can automatically sample the readings of the mechanical water meter. The sampling adopts a double sampling method, and the suction signals of two reed switches are detected sequentially, indicating the use of one unit of water.

Given the current shortage of water resources, implementing tiered water pricing is an inevitable trend. This requires the meter to have the function of recording monthly usage. The real-time clock module provides the necessary time values to implement this function.

The control interface of the board valve supports multiple electronic valves, making it convenient for users to develop the entire meter

The LCD interface of the board supports multiple LCD modules and can be customized according to user requirements.

The IC card interface fully complies with the ISO7816 international standard

The IC card interface can withstand 6000V electrostatic shock

The IC card interface has the function of preventing short circuit, overvoltage and overcurrent
