IC Card Smart Prepaid Water Meter --Lithium Battery

Feature:

1.Adoptone-piece shell structure, small simple and rugged beauty.

2.Fully seal design:Each part of the line devices adopt all epoxy sealed, no leakage of

electrodes, good sealing.

3.Low-frequency RF card(T5557 card) Technique:water meter data exchange using a

noncontact RF card technology, electromagnetic trigger ,guarantee water meter tightness

and improve the life of card.

4.Adoptimported ultra-low-powermicroprocessor,Circuitusingzero-powertechnology,

improve thebattery life, guarantee working life over 8 years.

5.Valve automatically sewage, blockades, anti-rust:Valve automatic switchregularly,

the instantaneous momentum for effective use of the water caused by the pipeline pressure,

the valve automatically sewage avoid valve fouling rust phenomenon.

6.Independent battery warehouse:Convenient property does not destroy the entire meter

seals to replace the battery.

7.Against outside electromagnetic attacktechnology:When external strong electric, magnetic attack,

water meter will automatically close the valve.

8.Alarm remaining water:When remaining amount of water in the water meter is equal to

the alarm value water, close the valve automatically to alert users to avoid water users

due tolack of water.

9.Data transfer:Engineering card can be used when water meter has fault, data transfer to

the new table, so as to achieve the purpose of the normal water and not affect the customer.

10.SupportWater, Electric, Warmer all-purpose-card, one card can charge 4 sets meter.

It is very convenient to one family that have some sets meters.

11.Limit Detection Function:Meter valve open or close in place, valve will immediately stop

rotating ,avoid the lockedrotor phenomenon, to improve the life of the battery and micro gear.

12.Misinterpret Automatic Correction Function:Whenthewater meterdue totheoutside

instantaneous attackalarm off valve,afterfive minutes,themeterwill automaticallydetect

the outside worldsituations,according tochangesintheexternalsituation,

executethe correspondingvalve operation.

Used:

Use to measure the amount of water flowing through the water pipe
