From: 2021-03-04

The plug-in water meter meets the technical requirements of GB/T778.1~3-2007 and CJ/T133-2012, which uses modern microelectronics technology, modern sensor technology, and smart IC card technology to measure water consumption, and transmit water data and A new type of water meter for settlement transactions. This water meter has the dual functions of mechanical counting and electronic counting. It is mainly composed of a smart card reader, a unique innovative electric valve, a flow collector and corresponding circuits. This kind of water meter can not only control the water consumption, but also The water consumption data can be stored, which improves the modern management level of the water supply industry, facilitates the use of users, and avoids the inconvenience caused to users by checking meter fees.

Card water meters are available in multi-jet, single-jet, dry and wet models. Different specifications and models are used in different environments. We upgrade the card water meters according to customer needs. Not only can the card be used for water, but also the card can be used for water. It is a multifunctional smart water meter,

The card-inserted water meter adopts the prepaid mode, that is, the water is purchased first and then the water is used: the initial available water amount of the water meter is zero, and the valve is closed. After the user opens an account and purchases water at the water sales point, he receives the user card. Put the card in the sensing area of ​​the corresponding water meter, insert the card and read the water available in the card, and then open the valve to supply water normally. After the available water in the water meter is used up, the valve is closed, and the user holds the card to purchase water at the water sales point, and then puts the recharged user card in the sensing area of ​​the water meter and repeats the first process.

Card water meters are generally placed indoors, so the requirements for their use environment are not high. It's just that this kind of water meter is generally placed near the kitchen, so there is a problem of preventing water erosion and oil smoke pollution. These problems are not difficult to solve now. The card water meter can generally meet the requirements as long as a reasonable sealing technology is used to prevent moisture. To prevent oil fume pollution, as long as you do some technical treatment on the IC card socket, such as adding a dust cover, etc., it can be solved.
