HDIL Smart IC Card Cold Water Meter (Vertical)
product overview
The HDIL type IC card vertical cold water meter (drinking water) uses advanced radio frequency cards as the medium for data storage and transmission, integrates the control valve with the base meter, has a sophisticated structure, and high reliability. This water meter is a new type of water meter that uses modern microelectronics technology and intelligent IC card technology to measure water consumption, transmit water usage data, and settle transactions. This product has a series of advantages such as advanced technology, excellent performance, reasonable structure, accurate measurement, stability and reliability. This product complies with GB/T778-2007, CJ/T133-2007, and CJ266-2008 standards.
Product Features
1. With microcomputer control technology as the core, highly integrated, stable and reliable.
2. It has a prepaid function, where users purchase water first and then use it. After the purchased water is used up, the water meter automatically closes the valve, and only users can open the valve after swiping their card to purchase water.
3. Adopting an LCD display screen, the display is intuitive and clear, and can show information such as remaining water volume, cumulative water consumption, valve status, low battery level prompt, wrong card prompt, etc., while retaining the word wheel and pointer display of the water meter.
4. Battery voltage monitoring function, built-in automatic alarm and valve closing when the battery is under voltage, and has anti-theft water function, and prompts to replace the battery. After the battery is powered off, the data is saved for a long time without loss.
5. Valve automatic maintenance function: The water meter automatically switches on and off twice a month to avoid blockage of the valve by sediment, impurities, etc. in the water, which may cause the water meter to fail to switch on and off normally.
6. Water cut-off alarm function: When the remaining water level reaches the set alarm value, the water meter automatically closes the valve to remind the user that the remaining water level in the water meter is low and to purchase water in a timely manner. At this time, the user can continue to use water by swiping their user card until the remaining water level in the water meter is zero, and the water meter will close the valve again to cut off water.
7. Non contact IC card (RF card) technology: using wireless transmission of data, completely solving the problems of card waterproofing, moisture resistance, and attack resistance.
8. Fully sealed design: The water meter adopts a dual waterproof seal, with sealing gaskets used between the upper and lower shells for sealing. The circuit board is then sealed with epoxy resin for sealing effect, with strong moisture-proof, waterproof, and dustproof performance and stable operation.
