 ? 
 ? 1. Automatically charges: prepaid mode, charging mode 
 ? Prepaid mode, that is to buy the water before the water: card water meter initial amount of water is zero, the valve closes. To the sale of water points to open an account, receive a user card to purchase water. Sensing area of ??the corresponding card meter, the card into the card meter to read the water consumption of the card, and then open the valve, the normal water supply. Card water meter, water availability is exhausted, the valve closes, the user card to the sale of water points to purchase water, and then the user after the recharge card into a card meter sensing area, repeat the first process. 
 ? After payment models, that is, post-paid in the first water: the card meter zero initial water availability, close the valve status. And administrative departments of the user maximum allowable first amount of water when the account pre-recharge to the user card. User card into the sensing area of ??the corresponding card meter card water meter reading of water available, and then open the valve, the normal water supply. Card water meter, water availability is exhausted, the valve closes, the user card to the sale of water points to make payments. Then water sales point for the user card recharge again, repeat the first process. 
 ? Automatically the price ladder 
 ? Card meter equipped with a clock, and can store up to 12 months of water consumption. User card into the card meter sensing area, the monthly water consumption of the card meter will write the user card. Each time a user to buy the water system from the user card automatically read the monthly water consumption and the price ladder calculation of water charges, to pay the user to purchase water. 
 ? 
 ? Up card, recycling transfer function 
 ? User card once purchased the successful transaction of the water meter for water only with the corresponding card if the card is lost, according to the software database management functions for a replacement card, the water will not lose or duplicate. 
 ? Card water meter needs to be replaced, the recycling transfer card inserted in the table to read out the data in the table, insert a new table, the old table information into the new table. 
 Mechanical and electronic two modes? 4. 
 ? Card meter retains the mechanical card meter print wheel and pointer display, while increasing the LCD. Even if the electronic part failure, the cumulative amount of water can also be read, according to the mechanical word round. 
 ? 
 ? Ganzhou smart meter product advantages: 
 ? 
 ? Soak seal in wet or underwater; 
 ? 
 ? 2. RF card technology, the user ease of operation; 
 ? 
 ? 3 battery is external, the replacement is more convenient; 
 ? 
 ? 4. Touch at the beginning of the design, anti-jamming capability, lower power consumption; 
 ? 
 ? 5. Pilot valve, without scale impact from the water pressure affect more secure and reliable (Patent No. ZL00 2 05 851) 
 ? General card meter with ball valve, the valve switch is susceptible to scale, the impact of water pressure. Ball valve and ball and the outer wall of a long soak in the water will have a scale, the scale so that frictional resistance increases, thus affecting the switching valve; ball valve resistance will be doubled when the water pressure increases, the switching valve will produce a great impact; 
 ? Pilot valve stopper works, free from scale, the water pressure; 
 ? Magnetic and hydraulic combination pilot solenoid valve, low power consumption, work, and the valve to open and close in the low-voltage state of a reliable, stable. 
 ? 6 base table, valves and other magnetic drive, special isolation seal design to solve the problems of ordinary card meter dynamic seal and leakage. 
 ? The ball valve and the motor directly connected, usually with a rubber ring seal, over time, is easy to produce deformation aging, thereby leaking; Long Kang card meter base table and the valves are magnetic drive, the isolation layer copper shell reinforced seal, and a maximum pressure of up to 35 kg, will not produce leakage; 
 ? 7. Anti-attack Design: antimagnetic, anti-vibration 
 ? Magnetic objects close to the card water meter, water meter card will be automatically closed valves, magnetic objects in order to prevent interference card water meter; 
 ? Water pipe vibration may lead to the rotation of the card meter, so that the card meter mistaken measurement, Dragon Sport card meter vibration false measurement can be removed because of water pipes. 
 ? Of Ganzhou smart meter product standards and the main parameters 
 ? A product technical standards for the implementation of CJ/T133-2001 GB/T778.1 standard 
 ? 2. Base table maximum allowable error to comply with the table of GB/T778.1B level requirements 
 ? (3) Compressive strength: 1.6MPa, 15min 
 ? Pressure loss: ≤ 0.1 Mpa 
 ? (5) working voltage: DC 3.6V ± 0.6V 
 ? 6 quiescent current: ≤ 20μA 
 ? 7. Current: 10000 
 ? 11. Motor-driven pilot valve movement margin: 0.05 Mpa ~ 1.0 Mpa 
 ? 12 clock timing error: ≤ 3s / day 
 ? 13. Reading distance: ≤ 5cm 
 ? 14. Medium temperature 
 ? A) cold-card meter medium temperature: 0 ℃ ~~ 40 ℃ 
 ? B) card meter medium temperature: 5 ℃ to 90 ℃ 
 ? Ganzhou Other features of the smart meter products 
 ? A measure function: the user through the user card to buy water, placed in the RF sensing area of ??the card meter, cumulative purchase water table, and calculate the actual amount of water; next purchase water, the user card automatically table water consumption and their status to the background management system. 
 ? 2. Display: the purchase of water, the remaining water, total water consumption and other parameters on the LCD display effective, the user can view through the user card table in the remaining water and the cumulative amount of water. 
 ? 3. Alarm function: battery voltage, remaining water shortage off valve, the valve failure, and misuse, card meter can display or valve control alarm. 
 ? 4. Parameter setting functions: the management according to their actual needs, the purchase of water through the user to set the alarm card meter of water, recharge limit, overdraft limit, and other parameters. 
 ? 5. To prevent water accumulation function: When the remaining amount of water is greater than recharge card meter limit, deny users the new purchase of water input to the card meter, and only when less than the recharge of the water remaining in the table limit before allow new share of water input card meter. 
 ? 6. Protection features: 
 ? Tips and record battery voltage protection function: battery voltage is too low and can be returned to the user card management system for the appropriate processing; depending on the size of the remaining battery capacity control valve breaking. 
 ? Ii magnetic interference protection features: card meter by external magnetic interference or card meter to win the trust of the line to destroy, you can close the valve to prevent users to illegally interfere with card meter run to reach through the card water meter and continue to water purpose; outside attack to undo, insert the user card to return to normal. 
 ? (Iii) the battery activation function: automatically at the beginning of each month in order to prevent the lag effect of lithium exist, the discharge operation. 
 ? 7. Up card function: when the user inadvertently user card is lost, through background management system for users reissued a user card and the last purchase water records complement written to the user card, the card meter automatically determine the final purchase water records on the table. 
 ? 8. Clock and calendar functions: the power to run the system calendar, automatic identification of a leap year, leap month. Parameter settings card before the card meter machine factory set calendar and clock. 
 ? 9. Check function: support to insert a check card in the card meter, all the data in the card meter read out, for the maintenance personnel, inspection and analysis of background management system.
