Dry antifreeze typeICThe card smart water meter adopts a meter valve integrated design, with a compact structure, strong linkage performance, high work consistency, and good anti freezing performance. The dial is made of high transparency polymer nano nylon, which will never freeze or burst, making it easy to install. This water meter is a high-tech smart water meter developed by our company. It has the advantages of intuitive widescreen electronic display, advanced design, high technological content, complete functions, accurate measurement, reliable performance, exquisite appearance, and convenient installation and use. It is suitable for measuring and charging tap water for urban residents, avoiding incidents of water theft, leakage, and overflow. Through electronic billing, the goal of water conservation and scientific management is achieved, while changing the traditional urban water supply management method, improving the modern management level of the water supply industry, facilitating user use, and avoiding the inconvenience caused by meter checking and charging to users.

1、 Antifreeze typeICUnique functional features of card smart water meter:

1Case:My company'sICThe smart water meter case is made of polymer alloy material (with high requirements for the percentage of chemical elements in the metal), which has a tight alloy structure, no pores, no inclusions, no small cracks, no internal stress, etc. The comprehensive mechanical properties are significantly improved, and there are no lead elements or other materials that do not meet safety and hygiene requirements.

2Movement:The digital display part of the water meter mechanism is made of tempered glass, and the main body is designed with a six directional water inlet and a multi beam mechanism to ensure stable rotating water flow of the liquid wheel. The national standard stipulates that the starting flow rate of small caliber is12-16rise/hThe starting volume of our company's water meter is6-12rise/hImproved measurement accuracy50%.

3Electric Suspension Ball Valve Technology:The five line valve is driven by a motor to complete the on-off valve action, and a dedicated motor drive circuit is designed. In addition to the two valve drive lines, the valve also requires a valve open position signal, a valve close position signal, and a common terminal. High power valve design, increased torque compared to before3Double, ensure smooth valve opening and closing to prevent valve jamming. Maximum input current450mATransmission ratio1500：1High output torque; The normal operating current of the actuator is less than60mAThe opening and closing time of the valve is less than1Minutes will not affect the battery life; When scaling or small impurities pass through the electric valve, it is not easy to get stuck when opening and closing the electric valve. Commonly seen in the market are3.6VMotor, maximum input current260mATransmission ratio850：1The output torque is relatively small, and when the electric valve is scaled or small impurities pass through, it is easy to cause jamming when opening and closing the electric valve.

4Ultra large capacity battery:Our company adopts17805/18505Lithium batteries have an actual lifespan of6-8In the year,14505The battery capacity is1800mA/h，17505/8505The battery capacity is2800~3500 mA/h.

5Low power design:The static power consumption current of our company's water meter is lower than5μAAccording to the national standard regulations25μABelow, our company's static current is lower than the national standard5More than double.

6Anti external electrical and magnetic attack technology:When attacked from the outside, the water meter will automatically close the valve.
