 ? Welcome to inquire: Mr.Tang 18,701,502,378 13,716,900,928 
 ? 
 ? 1. Automatically charges: prepaid mode, charging mode 
 ? Prepaid mode, that is to buy the water after the water: RF 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. The card into the sensing area corresponding to the RF meter, water availability in the radio frequency meter reading card, and then open the valve, the normal water supply. Water availability in the RF meter is exhausted, the valve closes, the user card to the sale of water points to purchase water, and then recharge the user card into the RF meter sensing area, repeat the first process. 
 ? After payment models, the first water postpaid: RF meter initial amount of water 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 RF meter, radio frequency meter reading of water available, and then open the valve, the normal water supply. Water availability in the RF meter 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 
 ? RF meter equipped with a clock, and can store up to 12 months of water consumption. User card into the RF meter sensing area, the monthly water consumption of the RF meter will write to 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 and the corresponding RF meter successful transaction time, 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 the RF meter needs to be replaced will be recycled into the table, 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. 
 ? RF meter to retain the word of the mechanical RF meter wheel and pointer, 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. 
 ? 
 ? The Ganzhou RF 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 RF 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 problem of a common radio frequency 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 RF meter base 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 
 ? Magnetic objects near the water meter of the RF, the RF meter will automatically shut the valve, to prevent the magnetic objects interfere with the RF water meter; 
 ? Water pipe vibration may cause the RF meter rotation, so that the RF meter mistaken measurement, Long Kang RF meter can be removed due to water pipe vibration false measurement. 
 ? The Ganzhou RF 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 RF meter medium temperature: 0 ℃ ~~ 40 ℃ 
 ? B) RF meter medium temperature: 5 ℃ to 90 ℃ 
 ? The Ganzhou RF meter products other functions 
 ? A measure function: the user through the user card to buy water, placed in the RF sensing area of ??the RF meter, 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 off valve, valve failure, and misuse, RF meter 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 in the RF meter water, recharge limit, overdraft limit, and other parameters. 
 ? 5. Prevent water hoard function: When the water remaining in the RF meter is greater than the recharge limit, refuse to users of the new share of water input to the RF meter, only table in the remaining water is less than recharge limit, and only allows share of water input RF 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: RF meter by external magnetic interference or radio frequency water meters to win the trust of the line to destroy, you can close the valve to prevent the user of unlawful interference RF meter run to achieve by RF water meter for water and continue to the purpose; 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 purchase water records last fill is written to the user card, radio frequency meter can automatically distinguish the last 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. By the parameters set the card to set the calendar and the clock before the RF meter machine factory. 
 ? 9. Check function: support to check the card inserted in the RF meter, and all the data in the RF meter read out, for the maintenance personnel, inspection and analysis of background management system.
