SKZS series IC card prepayment smart water meter is our newly water metering products, which use advanced intelligent technology to realize automatic collect, process, storage, digital display for data of water, and water supply can be under automatic control; With advantages of low consumption, strong antijamming capability, high integration level, more reliable, long life and simply installing, it becomes the most popular product in our normal using.
Features:
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
