HDIL type large-diameter IC card intelligent water meter

product overview

This series of large-diameter intelligent water meters consists of a base meter, a reed switch signaling device, a microcomputer control box, and an RF card information system. They are used to measure the water flow through pipelines and achieve prepaid management. The management department can access the data in the table at any time to facilitate the management of each user. This product meets all the requirements of GB/T778-2007 and CJ/T133-2012 standards.

Main functional characteristics

1. The various components of the product are designed with modularity, making maintenance extremely convenient.

2. This product adopts a special sealing process to ensure stable and reliable operation of the water meter underwater for a long time.

3. Adopting a large LCD screen display, the LCD screen sequentially displays information such as the purchased water volume, remaining water volume, valve status, low battery level prompt, wrong card prompt, etc., while retaining the character wheel and pointer display of the mechanical water meter.

4. Prepaid function: Various data are transmitted bidirectionally through an RF card, with water purchased first and then used later. After the water in the water meter is used up, the valve will automatically close, and the user can continue using the card by purchasing water and recharging it at the water sales department.

5. Alarm function: When the remaining water reaches the set alarm value, the valve automatically closes to remind the user to purchase water in a timely manner. After the user swipes the card, the valve opens; When the remaining water is used up and the valve is closed again, the valve can only be opened after purchasing water and swiping the card.

6. Automatic valve protection function: The water meter ball valve is opened and closed twice a month to prevent valve scaling and ensure stability and reliability.
