Infrared IC card water meter

◆ Product Features
The infrared IC card water meter is used to measure the flow rate of cold water in pipelines and also has an automatic charging function. The user hands over the water fee to the management department, and the management department writes the purchased water amount into the infrared IC card. After the user inputs the information in the infrared IC card into the water meter, the water meter will automatically open the valve to supply water. During the user's water use process, the microcomputer in the water meter will automatically reduce the remaining amount. After the purchased water is exhausted, the water meter will automatically close the valve and cut off the water supply. The user needs to purchase water again before opening the valve to supply water again.

Characteristics of lithium battery series infrared IC card cold water meter
1. Using infrared IC card technology, the card swiping distance exceeds 3 meters, solving the problem of difficult card swiping in special environments.
2. Zero power technology: The normal power consumption is basically 0 μ A, which greatly improves the service life of the internal battery and can be used for more than 6 years.
3. Electric suspension ball valve technology: It has the characteristics of anti lock and non scaling, and can achieve the effects of low pressure loss, low wear, low power consumption, rust prevention, and anti blockage.
4. Valve automatic drainage, anti blocking, and anti rust technology: The valve automatically switches on and off at regular intervals, effectively utilizing the instantaneous water impulse caused by pipeline pressure to achieve automatic drainage of the valve, avoiding phenomena such as valve rust and scaling.
5. Fully sealed design: All circuits are sealed with epoxy resin for good sealing performance.
6. Anti external electric and magnetic attack technology: When subjected to strong electric and magnetic attacks from the outside, the water meter will automatically close the valve.
7. By using infrared IC card technology and transmitting data wirelessly, it solves the problems of waterproofing, moisture resistance, and attack resistance.

Characteristics of dry battery series infrared IC card cold water meter
1. Using infrared IC card technology, the card swiping distance exceeds 3 meters, solving the problem of difficult card swiping in special environments.
2. Micro power consumption technology: powered by 3 No. 7 dry batteries, with an average battery life of over 2 years.
3. Multiple anti-theft water mechanism design: The battery can be replaced at any time, and when replacing the battery, it can warn of power failure and perform valve closing treatment.
4. Waterproof and moisture-proof design of battery box: The battery box cover is made of alloy material, which is smaller in size, wear-resistant, and has good sealing performance.
5. Electric suspension ball valve technology: with anti lock and non scaling characteristics, it can achieve the effects of low pressure loss, low wear, low power consumption, rust prevention, and anti blockage.
6. Automatic discharge, anti blocking, and rust prevention technology for valves: The valve is timed to open and close, effectively utilizing pipeline pressure and the instantaneous impulse of water to achieve automatic discharge of the valve, avoiding phenomena such as valve rust and scaling.
7. Fully sealed design: All circuits are sealed with epoxy resin, ensuring good circuit sealing.
8. Anti external electric and magnetic attack technology: When strong electric and magnetic attacks are carried out from the outside, the water meter automatically closes the valve.
9. By using infrared IC card technology and transmitting data wirelessly, it solves the problems of waterproofing, moisture resistance, and attack resistance.
