    automatically
4) Repairing card function: when user needs to repair card, meter reading card can 
    read all information inside card in order to repair card

Features: 
1) Infrared non-contacted intelligent IC card of patent technology, data transferred by 
    infrared to realize waterproof and moisture proof, and non-contacted 
    communication to prevent man-made destroying or mechanical damage
2) Power is lithium battery, which adopts micro power loss design and the using life is 
    more than 8 years and it can be changed
3) Anti-disturb design: it will be closed valve automatically to prevent man-made 
    destroying when meeting disturb or power is off
4) The circuit for the whole meter is pour sealing design to realize dustproof, moisture 
    proof and waterproof
5) Valve and meter is integrated: wet meter movement to make measurement more 
    accurately. It is of electric ball valve, low pressure loss, full close electro machine, 
    special designed gear wheel and large valve torque
6) Displayed by digital drum and LCD, which adopts technology of prevent dithering
7) Perfect system software for operation management to realize one card managing of 
    electricity, gas and water
