[0002] A water meter is an instrument for measuring water flow, most of which measure the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. It originated in the UK and has a history of nearly two hundred years. When choosing the specifications of a water meter, you should first estimate the size and range of the flow rate normally used, and then choose the water meter with the specification that is closest to the commonly used flow rate as the first choice. Electronic water meters are new water meters that use modern microelectronics technology and modern sensor technology. They are a great improvement over traditional water meters that generally only have the functions of flow collection and mechanical pointer display of water consumption.

[0003] Existing electronic valve-controlled water meters generally have a circuit board installed inside, and users then use it remotely through the Internet of Things. When the existing Internet of Things valve-controlled water meters are used underwater or underground, the water meters will be immersed in water for a long time. When the water meters with poor sealing effect are used, water flows into the interior, causing the electronic components to be easily damaged in a humid environment, which increases the number of maintenance times and reduces practicality.
