 ? 
 ? 1. Automatically charges: prepaid mode, charging mode 
 ? Prepaid mode, which is to buy water water: credit card water meter initial zero water availability, the valve closes. To the sale of water points to open an account, receive a user card to purchase water. The card into the corresponding sensing area of ??the card meter, credit card water meter to read the card in water availability, and then open the valve, the normal water supply. Card meter in water availability after the valve closed, the sale of water point user card to purchase water, and then recharge the user card into the card meter sensing area, repeat the process. 
 ? Postpaid mode, the first water payment: credit card water meter initial water availability is zero, 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 corresponding sensing area of ??the card meter, credit card water meter to read the water availability, and then open the valve, the normal water supply. Card meter in water availability after 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 credit card water meter will be the monthly amount of water into 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 water only with the corresponding credit card water meter successful transaction, if the card is lost, according to the software database management functions for a replacement card, the water will not lose or duplicate. 
 Transfer card? When swipe meter needs to be replaced, will be recycled into 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 card water 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 credit card water meter used ball 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 credit card water meter dynamic seal and leaking. 
 ? 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 credit card meter table and valves are used magnetic transmission barrier reinforced with copper shell seal, the maximum pressure of up to 35 kg, will not produce leaking; 
 ? 7. Anti-attack Design: antimagnetic, anti-vibration 
 ? Have magnetic objects close to, credit card credit card water meter water meter will automatically turn the valve to prevent the magnetic objects interfere with credit card water meter; 
 ? Water pipe vibration may cause the rotation of card meter card meter error measurement, Long Kang credit card water meter removed due to water pipe vibration false measurement. 
 ? Ganzhou card 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) credit card cold water meter medium temperature: 0 ℃ to 40 ℃ 
 ? B) card meter media temperature: 5 ℃ to 90 ℃ 
 ? Ganzhou card water meter 
 ? A measure function: the user through the user card to buy water, placed on a card meter RF sensing area, cumulative purchase water table, and calculate the actual amount of water; the next time the user to purchase water user card automatically when the water table the amount of 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 valve clearance, valve failure and misuse of credit card water 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 water meter in, recharge credit card lower limit of the 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, the only table in the remaining water is less than recharge limit, and only allows quantities of water purchased new 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 destruction of the card meter to win the trust of the line, you can close the valve to prevent the user of unlawful interference card meter run to reach the water meter by credit card and continue to water purposes; outside attacks undo, insert the user card back 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 supplement the record written to the user card, credit card water meter can automatically distinguish the last purchase water records on the table.
