HC Smart Home Network There are three different water meters on the test bench.

The first is the most common, and it is also the rotary-wing water meter installed in the homes of most Hangzhou residents. After turning on the faucet, the dial inside keeps rotating with the size of the water flow.

The water meter in the middle drags a "tail", which is actually a wire. Zhao Jianliang said that this is an electronic remote water meter that uses IoT technology. With this kind of water meter installed, the water company no longer has to send someone to knock on the door to read the meter, and can directly grasp the city's water meter online. This kind of water meter is also the direction of future development, but it has not yet been applied in Hangzhou.

The last water meter looks completely different from the water meters we usually see. It has a square head and a square head, but a bit like a gas meter. According to reports, this is a prepaid water meter that can be swiped and used.
