IC card meter

High reliability

And no Lou in the outside occasionally contacts, is not easy to be damaged.

IC card is the plug-in, card chip sometimes suffers extruding or by strong magnetic field interference easily damaged, the contact card short circuit is easy to damage when chip, another card contacts within the bayonet socket and contacts long exposure to easy oxidation, or loss of elasticity, have contact undesirable reflection.

Prevent copying

This form can be "9999" area, the same table, the same time to buy, the same dosage, and get the purchase of the password is completely different. So the same area, different table, different number of buy, buy different dosage is different, it is a kind of without any carrier only data password.

IC card chip production is very simple, and bare outside, very easy to crack, copy, causing the loss of water supply unit.

High sealing

And the main input methods is now, with key way, button below after two seal to deal with, so the whole table preventing moisture is very good.

IC card table with bayonet socket, if have the moisture is prone to chip internal, corrosion components, cause a short circuit and make the phenomenon such as loss of data.

Convenience to buy

The code in the practical application of products in the process of the operation is simple, every time when water enter your pin to eight, the code is table is special, secret performance is extremely strong, and can always inquires and the balance usage, the user can choose to buy code postal service hall, also can never leave home through the telephone and the Internet to buy the code, great convenience to the residents' lives.

IC card itself is a kind of medium, and each time the user fee after purchase, must will return to insert your card, inside the watch to realize open valve use, have certain limitation.

Prevent remove and security

The research and development, making the generation and my company now another product electronic seal, and the combination of meter installation is completed in generation, using electronic seal the whole table body and pipe body part sealed off and set a global only passive key, once the user seal the destruction, through the electronic reader can be found, thus responsibility.

IC card table does not have this function.
