Product Features
1. The dry water meter movement is made of high-strength ABS plastic, and the movement does not come into contact with water. The word wheel display is permanently clear, and it will never corrode in humid environments.
2. Card swiping area: Humanized design ensures accurate and effective transmission of card information by users, and the card slot is fully enclosed without affecting the waterproof performance of the entire meter.
3. Appearance: Exquisite and beautiful, compact in structure, occupying a small installation area, making it easy for users to install indoors.
4. It can support the functions of one meter, one card, and multiple meters, which are fast, simple, reliable, and greatly improve service efficiency.
5. The waterproof design of the water meter is a patented technology of the company. All electronic devices are sealed with food grade electronic sealing adhesive, which has high waterproof performance, safety and reliability, and has reached the highest waterproof level IP68 standard.
6. The automatic detection function is tested every 15 days to ensure reliable operation in the event of various interferences and prolonged use of the meter.
7. In case of magnetic attack, battery undervoltage, or residual water volume below the set alarm water volume, the water meter will automatically close the valve and display an alarm message in Chinese characters.
8. IC card prepayment: Users pay first and then use water, completely solving the problem of household fees.
9. Ladder water prices: According to policies, water prices are divided into different tiers and different prices are implemented within different quota ranges.
10. Anti dismantling heat shrink film: It prevents malicious dismantling of the meter by humans, providing anti-corrosion and never rusting effects on the joint, making it easy for maintenance and repair after use.
11. Battery: The theoretical lifespan of the national standard ER14505M battery is 6-8 years. Our company uses ER18505M lithium sub waterproof battery, and the actual lifespan is 6-8 years. The battery capacity is 1.5 times higher than the national standard. (ER14505M battery capacity is 2000mA/h -- ER18505M battery capacity is 3500mA/h).
12. Static low power consumption: The static power consumption current of the water meter is less than 5 μ A. National Standard 25 μ Below A, the static current is more than 5 times lower than the national standard.
