 ? Welcome to inquire: Mr.Tang 18,701,502,378 13,716,900,928 
 ? 
 ? 1. Automatically charges: prepaid mode, charging mode 
 ? Prepaid mode, that is, first to buy the water, the water: prepaid water meter initial water availability is zero, the valve is closed. To the sale of water points to open an account, receive a user card to purchase water. Card will be placed in the corresponding pre-paid water meters of the sensing area, pre-paid water meter read cards, water availability, and then open the valve, the normal water supply. Pre-paid water meters in water availability after use, the valve closes, the user card to the sale of water points to purchase water, and then recharge after the user card into the pre-paid water meter sensing area, repeat the first process. 
 ? Post-paid mode, the first water payment: prepaid 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 ??pre-paid water meter, prepaid meter reads water availability, and then open the valve, the normal supply. Pre-paid water meters in water availability after use, 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 
 ? Pre-paid water meter equipped with a clock, and can store up to 12 months of water consumption. User card into the pre-paid water meter sensing area, pre-paid 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 purchase once the water only with the corresponding pre-paid water meters to successful trading, if the card is lost, according to the software database management functions for a replacement card, the water will not lose or duplicate. 
 ? When pre-paid water meters need 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. 
 ? Pre-paid water meters to retain the mechanical pre-paid water meters in the word 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 pre-paid water meter product advantages: 
 ? 
 ? Soak seal in wet or underwater; 
 ? 
 ? 2. Prepaid 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 pre-paid water meters with ball valve, 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 ordinary pre-paid water meter dynamic seal and leakage problems. 
 ? 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 pre-paid water meters of the base table and valves are used in 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 pre-paid water meter, pre-paid water meters will automatically close the valve to prevent the interference of magnetic objects pre-paid water meter; 
 ? Water pipe vibration may lead to pre-paid water meter rotation, so that pre-paid water meters mistaken measurement, Long Kang pre-paid water meter removed due to water pipe vibration false measurement. 
 ? Ganzhou pre-paid water meter product standards and the main parameters 
 ? A product technical standards for the implementation of CJ/T133-2001 GB/T778.1 standard
