2. Use a built-in lithium battery, which can be used for more than 6 years.
3. Adopt special electric valve, low power consumption, low pressure loss, and reliable switch.
4. Display function: LCD liquid crystal display, display residual water, valve status, battery status.
5. Parameter setting function: the management can set the alarm water in the water meter and the limit of recharge and other parameters according to the actual needs of the user.
6. Control function: when the remaining amount of water reaches the alarm limit, the valve automatically closes, the liquid crystal display "purchase card", "turn off valve" prompts the user to buy water in time. After swiping, you can use the remaining water. If the remaining amount of water is 0 m cubed, the valve will be closed automatically, and the user must buy water before use.
7. Error operation prompt function: the liquid crystal will display the error information code when the operation is missed.
8. Non-volatile memory is adopted in the water meter. The data will not be lost when the power is lost, and the data can be saved for more than 10 years.
9. Waterproof function: the circuit is fully sealed and can work properly in a high humidity environment.
10. Monthly self-check function: the monthly automatic switch valve of water meter prevents corrosion of valve.
11. Adopt inductive (non-contact) IC card, which has the characteristics of strong confidentiality, anti-interference, wear resistance and simple operation.
12. One-piece design, beautiful and sturdy, waterproof, anti - attack, anti - damage.

2. Operation instructions
(1) to open an account: before using the new user to the water administrative department to open an account and get your own card, enter the user information management department and according to the user's payment will be the equivalent of water by writing user card read-write card device, the user can use.
Charge card: after opening an account, you will need to put the card data into the table, place the card in the "sensing zone" and the liquid crystal display "code..." When the liquid crystal displays "good", the water is successfully entered into the water meter and the valve opens to water.
For example, the total amount of water can be read directly from the dial table.
(4) top-up: with the use of the user, when the surplus water reach the lower limit alarm value after 2.0 m (can be set up management department), the valve automatically shut down, the liquid crystal display (LCD) "purchase" valve ", "alert users to buy water. At this point, the user brushes the card again, the valve opens, and can continue to use the remaining water. If the remaining amount of water is 0m to 0m, the valve will be closed automatically, and the user must go to the management department to recharge and continue to use.
The user should properly keep the water card. If there is any loss, the user should go to the designated management department to complete the card.
3. Precautions!
If there is a magnetic interference, the water meter will automatically close the valve and display "alarm". After the interference disappears, the card will be restored automatically.
When the operation is misinterpreted, the liquid crystal display code is explained as follows:
Code instructions
ERROR20 card type error (not identifying this type of card)
ERROR21 Settings card data error
ERROR22 user card user Numbers do not match
ERROR23 user card purchase number does not match
ERROR24 buys more than the amount of excess
ERROR25 multiple card error after opening an account
ERROR26 user card flag is not correct (non-user card)
There is no data in the ERROR27 table that USES a pin card error
ERROR28 user card can make mistakes in the process
ERROR29 pin card transfer to new table data back error
ERROR30 pin hukka turns the data back and writes the error
ERROR13 finder error, indicating that the antenna has no card
The shut-off valve caused by mistake operation will be opened automatically when the remaining amount of water is not 0m cubed, and it can be used normally.
When the liquid crystal display undervoltage, the relevant technicians should replace the battery.
We apologize for the difficulties caused by the failure of this table. However, please do not remove the water meter. You should contact the water supply department immediately and ask the professional to repair it.
For the rights of users, please keep the seal intact.

2. Installation precautions
The size of the meter shall be determined according to the amount of flow of the pipe.
For gauging accuracy of water meter, it should be avoided in the vicinity of elbow, valve or pump. If necessary, it should be installed with long straight pipe section. If necessary, the rectifier should be installed.
The location of the water meter is to avoid exposure, freezing, pollution and water, and the reading and removal are convenient.
(4) for water meter measuring accuracy, the direction arrow on the table and in the direction of flow must agree, no special instructions, water meter must be installed level (vertical installation should choose vertical table), make up, literal pipe outlet (tap) should be higher than that of water meter.
In order to avoid the failure of water meter, it is necessary to flush the sand, sand and linen in the pipeline.
When the meter is loaded, install a control valve in front of the watch to make it easy to disassemble and close the front valve of the water meter.
The cold water meter shall be installed in a boiler or a heat source into the water pipe and shall prevent hot water from returning to the water meter.
The water meter should not be connected directly with the pipe, the water meter and the pipe should be connected by connecting tube, sealing gasket, connecting nut, and when breaking the table, do not force hard to avoid twisting the case.
When the water is not used in water, such as the installation of water meter in a certain position, it is caused by the unstable pressure caused by the pressure of the pipe and the change of water temperature.
The wet water meter is immersed in water, and water or bubbles are normal under glass. The use of the literal pollution affects reading, generally because the pipe is old, the water quality is poor or the position is caused by the end of the pipe.
Transport and storage
1. The water table after packaging should be handled with care, avoiding severe impact.
2, the environment temperature 5 ºC to 50 ºC, relative humidity < 90%, prevent the strong electromagnetic field and direct sunlight.
3. Layer height must not exceed 5 floors.
4. The storage warehouse shall be the indoor environment of dry, ventilated and non-corrosive medium.
The attachment,
One, two joints.
2. Two connecting nuts.
3. Two sealing pads.
4. Radio-frequency card.
