YTF-FS IC Card Prepaid Meter with Valve 2-in-1 (Combined) Smart Water Meter
UNIQUE CHARACTERISTICS
1. Meter with valve 2-in-1(combined) design, compact comformation, high conjunctive capacity, high working consistency, good water-proof performance
2. The valve, adopt the design of high-power valve, the torque force increased three-fold than before, to ensure the switch on/off valve in right position, to avoid stuck.
3. The meter glass, meter glass adopt food-grade transparent, high strenth synthetic glass, prevent foreign objects damage to water table effectively, good anti-frozen performance, at the same temperature, it won't be caused any loss by overflowing even water meter frozen.
4. High strength waterproof performance, the water proof performance from our IC card water meter is our patent technology, all electric components are using food grade professional electronic potting adhesive sealing, waterproof performance is high, safe and reliable.
5. Tamper shrink membrane, to prevent malicious down table, and on the joint to effectively anti-corrosion, never rust function, easy to repair and maintenance after use
.
6. The card slot : the humanization design to ensure that the client swiping the card in quasi effective, the card slot is fully closed, it does not affect the whole table waterproof performance.
7. Battery: battery life is 6-8 years in theory according to GB14505, our company adopt waterproof 18505 lithium manganese battery, the real life is 6-8 years, the battery capacity improved 1.5 times higher than the national standard. (14505 battery capacity of 2000mA / h - 18505 battery capacity of 3500 mA
8. IC pre-paid smart card has three points star configuration, swipe the card quick, accurate and convenient, high sensitive and reliable with transmiting signal.
9. Low static power consumption: the static power current from our company meter below the 10|JA, GB 25pA below, our static current is more than 2.5 times lower than the national standard.

YTF-FS MULTI FUNCTIONAL MANAGEMENT SYSTEM
YTF-FS MULTI FUNCTIONAL MANAGEMENT EQUIPMENT AND RF IC CARD
Multi functional card-writer is suitable for the management of RF IC card pre-paid smart water meter from the series of DL of our brand "HUI YI", networked with the computer, the appearance is small and beautiful. Card-writer adopt general USB interface with the computer data transmission, concise and easy to use.
Non -contact IC card through radio waves, using the Manchester code to read and write in the card information, total-sealed, non-contact, water proof, anti-damp, bending resistance, anti-abrasion, the card will be wiped by across any direction from the surface of induction area, each non-contact IC card has a unique serial number, it's extremely hard to crack and copy, it is the development trend of IC card in future, our country adopt the technique of RF ID card for The second generation of resident identification card.
