WF8002 is a professional and unique chip for metering of water meters and gas meters .Packaging type: QFN32 4*4mm It can work connecting with few external RC components.As connecting with PCB coils, the chip can detect circle number of metal rotor, then convert circle number into pulse signal for output. It embedded in unique and mature anti-interference algorithm with stable performance, and widely used in smart water/gas meter industries.
l Stable working distance: 4~10 mm (depends on shape of metal plate)
l Support forward and reverse running detecting
l support metal sheet insertion alert and module apart alert.
l power consumption less than 3uA
l Detecting frequency is adjustable to meet business and residential water meter.
l To resist interference and power supply fluctuation, the chip embedded in a strong anti-interference algorithm
l Be able to embedded M-bus standard 188 protocol.
l Support Open-CPU solution with dense flow storage,accept interval storage and period storage.
