how EMI IC Card prepaid water meter works

This series of water meters are Non-contact (RADIO frequency card) prepaid type. The user will pay for the water to the management department, and the management department inputs the amount of water purchased into the IC card through the software. After the user IC card (RF card) is close to the induction area, the water meter will automatically record the water purchase information. The water meter will then automatically open the valve to supply water. As water goes the microprocessor in the water meter automatically checks the remaining water. When there is not enough water left, it triggers an alarm function and reminds users to buy water. the meter automatically closes the valve to cut off the water supply till the purchased water is used up.

User Guide:

After the IC Card smart water meter is installed, you need to obtain relevant information from the IC card to start and operate normally. When using the IC card, the IC card must be placed to the card sensing area (if the display does not display, shake the IC card up and down, left and right). When the display shows data, the card can be removed. When the intelligent water meter delivered from the factory, there is 2 cubic meters of water for user verification and test. Before the intelligent water meter is officially used, the data in the prepaid water meter needs to be cleaned. After cleaning, place the user card and corresponding water near the sensing area (RF card) or insert it into the card slot (contact type). After the data is displayed on the display screen,put away the card. It can be used after the valve is opened.

☆ The diameter of water meter shall be determined according to the pipeline and service flow.

☆ The installation position shall avoid direct sunlight, freezing, pollution and flood.

☆ The water meter must be installed horizontally with the front facing upward, and the arrow direction on the meter case is consistent with the water flow direction, which is convenient for disassembly and operation.

☆ Before installing the water meter, the stones, sediments, linen and other sundries in the newly installed pipeline must be cleaned to avoid the failure of the water meter.

☆ In order to measure correctly, the faucet should be higher than the water meter; The length of the straight pipe section in front of the meter shall not be less than 10d, and the length of the straight pipe section behind the meter shall not be less than 5D, where D is the nominal diameter of the water meter.

☆  the water meter shall not be directly connected to the pipeline. The water meter and pipeline shall be connected through connecting pipe, sealing gasket and connecting nut. Do not use too much force during disassembly to avoid twisting the case and affecting the normal operation of the water meter.

☆ It is forbidden to leave anything above the water meter. Pay attention to moisture-proof. It is strictly prohibited for water vapor and water droplets to penetrate into the water meter controller, damage the control system and affect the normal use of users.

☆ The maximum battery replacement time is 6 years.
