Users who should go to the business office of the administrative department to open an account and file to purchase the corresponding water meter when using this meter. The user card must be used on the prescribed table when it is first used, otherwise it may cause unnecessary losses.
Place the radio frequency card near the card reading sign area of ​​the plastic housing of the water meter, the LCD display "rdIC" means the radio frequency card is detected, if it displays "END" it means the card is operating normally, if it displays "Errxxx" it means there may be a problem, please try again Put the card position,
try again, if you still have such problems, please contact the management department. When the remaining amount of the water meter is less than the set alarm value (the alarm value is set to be 2.0m3 when the meter is shipped from the factory), the valve is closed and the alarm is displayed, and the sign of "please recharge" is displayed at the same time. The IC card water meter reminds the user to recharge in time;
When the remaining amount decreases to zero, the valve is automatically closed, and the user needs to purchase a new recharge card to open the valve.
When the radio frequency card has a failure in the description 2, the transmitter will also be closed, and the valve can be opened after the failure is eliminated. If the user loses the card, the management terminal will go through the corresponding card replacement procedures. After the card is reissued in this system, it can still be used if the original user finds it.

Accuracy grade is B grade, adopting standard: CJ/T133-2007 IC card cold water meter
Maximum allowable error
From including the minimum flow rate (qmin) to excluding the decomposition flow rate The maximum allowable error in the low zone of (qt) is ±5%.
The maximum allowable error in the high area from the decomposition flow rate (qt) to the overload flow rate (qt) is ±2%.
The working pressure is not more than 1.0MPa, and the power supply voltage is 3.6V lithium battery. Less than 5 years of flow parameters.

Description 1: The remaining amount can be displayed as a negative number
Description 2: The content of the fault message
The content of the fault v Display content
Battery undervoltage "undervoltage" sign
Flow Sensor failure "flow" sign
The current state of the valve When the valve fails, the "valve open and valve closed" sign will be displayed. When the valve is open when there is no fault, the "valve open" sign is displayed. When the valve is closed, the "valve closed" sign is displayed.
Please recharge status When the remaining amount on the meter is less than the alarm parameter value, the "please recharge" sign is displayed.

Before installation, you should first clear the hemp, sand and other debris in the pipe to avoid blockage of the water meter.
The IC card water meter must be installed horizontally, and the arrow on the water meter housing must be consistent with the direction of water flow during installation. In order to ensure the accuracy of the flow meter, it is required to leave a straight pipe section with 6-12 times the nominal diameter in front of the water meter, and a straight pipe section with 4-6 times the nominal diameter at the back.
