◆ Instructions for use
The non-contact IC card cold 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 IC card. After the user inputs the information in the 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 non-contact IC card cold water meter
1. By adopting non-contact IC card technology and transmitting data wirelessly, the challenges of waterproofing, moisture resistance, and attack prevention have been solved.
2. Zero power technology: The normal power consumption is basically 0 μ A, which greatly improves the service life of the internal battery, with a battery service life of 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.

Characteristics of non-contact IC card cold water meter for dry battery series
1. By using non-contact IC card technology, data is transmitted wirelessly on the outer wall of the water meter, solving the problems of waterproofing, moisture resistance, and attack resistance.
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.

◆Performance comparison between non-contact IC card water meter and ordinary IC card water meter

Non contact IC card water meter		Ordinary IC card water meter
moisture resistance	No exposed electrodes, fully sealed circuit, good moisture resistance	There are exposed electrodes, and the circuit can only be partially sealed, resulting in poor moisture resistance. In humid environments, IC cards may experience data errors, and long-term use may cause contact rust and corrosion
waterproofness	Wireless data transmission, fully sealed, can work normally when placed in water	Data transmission through electrodes, unable to work in water
Confidentiality	Wireless data exchange with high confidentiality	Wired data exchange with poor confidentiality
Anti attack Prevent water theft	No exposed electrodes, external strong electric fields cannot attack it	Attacking the exposed electrodes with an external electric field (such as lighters, gas igniters, 220V voltage) can easily cause the system to malfunction without any visible traces, making it extremely easy for users to steal water
battery lifetime	Zero power technology with a battery life of over 6 years	How many microamperes of static power consumption is there, and the battery life is generally 2 years
Base table	Produced on an Italian production line, in compliance with international standards for overall meters, purchased as a whole, with high precision, low starting flow rate, and B-level meters	Kit assembly, low precision
valve	Electric ball valve, no pressure loss, specially designed gearbox, high torque on/off valve	pilot	The pilot hole is prone to blockage, causing water to not open and unable to close after use
		solenoid valve	Tap the pipeline to open the valve
		Disc valve	High pressure loss, loose switch valve
