◆ prepaid function: two way transmission of water information through IC card water meter, first purchase water and then use water, no charge automatic valve closing to stop water.
◆ with the function of step water price: the property management department can set different steps for the water meter according to the local practice, and complete the charging according to the step water consumption. Automatic settlement every month. The total water consumption information of the current month will be recorded automatically when arriving at the settlement date. The settlement date can be set freely.
◆ one card function: the table supports one card and multiple tables, and can complete one card for electricity, gas, cold and hot water.
◆ display function: users can directly view various information of the water meter, such as the current water consumption, remaining water consumption, cumulative water consumption, on-off valve status, power shortage prompt, etc., which are clear and intuitive.
◆ warning function: when the residual water reaches the set alarm value, the water meter will automatically close the valve to prompt the user to purchase water in time, and the user can continue to use it after swiping the card until the water volume is zero.
◆ valve closing function: when the remaining water volume is zero, the water meter will automatically close the valve. As long as the user purchases water and swipes the card, the valve can be opened for use.
◆ low voltage alarm function: when the battery is short of power or the battery is replaced, the water meter will automatically close the valve.
◆ storage limited function: when the recharge exceeds the limited quota, the water meter will not read the water purchase quantity in the card until the sum of the remaining water quantity in the water meter and the current water purchase quantity is less than the limited quantity.
◆ anti attack function: when the IC card water meter is attacked by strong magnetism or strong electricity, the water meter will automatically close the valve. As long as the external interference is removed, the valve can be opened and the attack information will be recorded automatically.
◆ function of drainage and rust prevention: the water meter automatically turns on and off the valve once a time to complete the automatic drainage of the valve and prevent the valve from scaling, rust and other phenomena.
◆ functions of "three proofs": fully sealed design, waterproof, leakproof and attack proof. The common design of the battery compartment on the top of the shell makes it very convenient for the management department to change the battery.
◆ micro power consumption design: the static working current is less than 5ua, ensuring the battery service life is more than 6 years,
◆ small pressure loss, small resistance of opening and closing valve, and less power consumption.
◆ international PPO data suitable for pure water request shall be selected for movement parts, so as not to pollute water quality.
