Product Description
Radio frequency card prepaid water meter is the new measuring instrument employing the microprocessor to realize water collection, processing, display, and reserving. It is the best choice for realizing intelligent control by most of tap water administrative bureaus, ideal for enhancing public awareness of saving water. This meter has many patents. Compared with traditional way ,it can control user's overspend by prepaying for an IC card.
Note: Cubic meter (m3) and U.S. gallon (USG) for option
Working conditions:
Water temperature
≤40°C for cold water meter
≤90°C for hot water meter
Feature:
1. RF card water meter use pre-paid way to achieve the new management mode of "payment first before use"
2 .Show the different level price of the water, one card can be used for several meters.
3. Double reading display: mechanical and electronic reading
4. Unique battery protection
5. Stable performance, wide application
6. Low power consumption, long service time
7. Electronic part is vacuum sealed.
8. Anti-jamming and resist exterior magnet interference.
Smart functions:
1. Auto-control: Closing and opening valve according to programmes.
2. Cryptographic security: Generating and identifying IC card password automatically, one card for one meter, not interchangeable.
3. Anti-magnetic interfered: The valve closes automatically,when interfered by magnet, and opens by swieping IC card if interference is eliminated.
4. Warning function:The valve closes automatically,when remaining balance is 2m3 (set according to user' s requst),and opens by swieping IC card.
5. Low power warning: When power is insufficient, LCD reminds you to replace of batteries.
6. Closing valve if not replacing the battery in time after above reminding.
7. LCD: LCD displays used amount, remaining balance, valve status, power status, err. codes and other information.
8. Checking data: LCD no display normally, checking data by swieping IC card on the meter.
9. Anti-plugging function: Self-cleaning valve by the program to keep valve in good condition.
10. Data feedback: Date in water can feedback to managing system by card, convenient for management.
