Intelligent water meter is a new type of water meter that uses modern microelectronic technology, modern sensing technology and intelligent IC card technology to measure water consumption, transfer water consumption data and settle transactions. This kind of water meter has the following three advantages: first, without manual meter reading; Second, save labor cost; Third, improve the efficiency of meter reading.
Smart water meters adopt point-to-point remote transmission mode. If a water meter has a problem, it will only reflect the problem of the user's water pipe, and will not affect other users, which also brings great convenience to the maintenance of water meters and meter reading work in the later stage.
