IC card water control function "pay first and then use water" after the development of social civilization to a certain height, it is impossible to become the only control method for water fee collection, and at the same time in industrial developed countries, they are applied within the enterprise to save water control rating In addition to the planned indicators and actual water consumption, there are colleges and universities for internal water conservation. The water use of IC cards in the residence halls of students staying in the school also uses the IC card water control device to control. Rarely use ordinary water meters, and do not advocate the use of water before charging. For them, this issue is related to the issue of “human rights†for people who drink water. People who have no money still have the right to survive because they do not have the money. Therefore, such measures are not implemented. Moreover, the current power supply and gas supply still maintain the principle of using post-payment first, the economy is advanced, the living standards of the residents are high, and people’s ideological realm is also improved. The law of paying by water first and then does not cause arrears in water charges. Social issues, so that the progress of social civilization, this kind of prepayment measures is not an ideal measure. Therefore, the prepaid form of IC card water meters is gradually shifting to the direction of remote transmission and automatic reading systems.
Applications <br> <br> mainly used in schools, mining, hospitals, boiled water room, bath and other areas, the use of water after the first payment management, intelligent management of automated measurement occasions.
Installation Precautions
1, the water control device itself has a direction of flow, the installation must pay attention to the direction of the bottom of the water control casing arrow and the direction of the water flow. If there is no swiping water or solenoid valve is not open, it is estimated that the installation direction of the water controller is wrong.
2. It is forbidden to directly input 220V power to the water control machine, otherwise the consequences are your own. Must pass the power adapter to output 12V direct current power supply, positive and negative two lines receive the water control machine power line, if does not show please invert the connection, the water control machine has the circuit protection, the connection will not burn. If the line is not long enough, please extend it by yourself.
3, the water inlet nut of the water control machine should hold the water control machine with one hand when tightening, and hold the nut with one hand and clamp the nut gently, it should not be too hard. The outlet must be held in one hand with a thin arm plate to hold the hex screw, and the other hand to use a wrench to grip the nut and gently apply force. It is forbidden to use brute force, otherwise the consequences are at your own risk.
4. Two sets of water meter connector (nut, copper sleeve, silicone pad) are distributed in the water controller package. Please note that the nuts of the two water meter connectors are not the same. The nut with a higher column is installed in the water control. At the inlet side of the machine, the lower column is installed on the side of the outlet. According to the length of the water control machine, the water meter connector can be connected on both sides of the water pipe, and the water control machine can be tightened.
5, the power supply is best installed in a safe place to install a general electrician socket, not easy to be splashed with water. The power adapter must be firmly attached and not easily fall. Note that the outlet must be dedicated to 220V mains electricity. Unsafe wiring is prohibited.
Applications <br> <br> mainly used in schools, mining, hospitals, boiled water room, bath and other areas, the use of water after the first payment management, intelligent management of automated measurement occasions.
