Features: ○ unique battery compartment design, easy to replace the battery. ○ "three defenses" feature: fully sealed design, waterproof, leak-proof, anti-attack. ○ with prepaid capabilities: the ability to achieve a new model of water "to buy water, water" management. ○ self-cleaning function: automatic switching valve once the meter regularly, avoid fouling, rust valve phenomenon. ○ micro-power design: quiescent current of less than 6UA, ensure that the battery life of more than six years. ○ Card features: The table supports a card table, enabling water, electricity, gas, heating card. ○ electric valves made of stainless steel floating ball valve, pressure loss, small switch valve resistance, low power consumption. ○ LCD liquid crystal often significant amount of water available, total water consumption, valve status, battery status, and other parameters. ○ Movement components using high-strength ABS plastic as the main raw material, reliable performance and long service life. ○ battery voltage indicator: low battery, LCD "Brown" and automatically close the valve, to remind the user to replace the battery. ○ and replace that function: the use of national standards designed to connect the same size as ordinary water, no need to change the pipe can be replaced. ○ water can set the alarm when the remaining water reaches the alarm value, the valve automatically closes, LCD "card purchase," "off valve," to remind the user to purchase water, then the user can be painted once a card, you can use the remaining water . If the remaining water to 0m3, the valve automatically closes, the user must purchase before opening the water valve using a credit card.
