IC 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.
1. Water Meter: Two types of photoelectric reading water meters, with valve and wothout valve.
2. Collector:Gets data from meter and sends to centralizer; and provides power to meters.
3. Centralizer:Through collector, gets data and saves them, sends orders to meters.
4. Data Center:Consists of PC,software,printer.
--Area:Setting area code.
--Resident managing:Controlling each account for permited amount and charging mode.
--System log:Saving and checking the system log.
--Authority:Authority rights to different operators.
--Revising time:Revising devices's time in the system automaticly when reading data on time.
--Informations:Saving and checking history data;checking the informations by number,address,name,phone.r.
1. Product's Type- With valve, without valve (integrated), without valve (separated)
2. Control Mode- IC card prepayment, one card can manage for six water meters
3. Display Method- LED/LCD display, which can work normally under all kinds of environments, and it is easy to read clearly in the night
4. Working Manner- Alarm/overdraw function, largest reserves can be set
5. Protections- Take imported single chip microcomputer, which can handle real-time monitoring and measuring, once abnormal situation occurred or owe fee already, it would close valves automatically
6. Interface Protection- Perfect interface protection circuit, which keeps the meter from all kinds of vicious attack, no damaging for meter, no lose for data, and no delay for active.
7. Reliable Design- Valve control meter take intelligent valve control technology to drive professional ball valve with high performance and low power, to make smaller loss of water meter pressure and more reliable work
8. Communication Mode- Pulse, infrared, RS485 interface are optional
