The user gives the water fee to the management department, and the management department writes the amount of water purchased 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. When users use water, the microcomputer in the water meter will automatically subtract the remaining amount. After the purchased water is used up, the water meter will automatically close the valve to cut off the water, and the user can only open the valve to supply water again after purchasing the water again.
trait
1. adopts the patented technology of contactless IC card to transmit data wirelessly on the outer wall of water meter, which solves the problems of waterproof, moistureproof and attack prevention.
2. The patented technology with zero power consumption greatly prolongs the service life of the built-in battery and ensures that it can be used for more than 8 years.
3. Patented technology of electric suspension ball valve: it has the characteristics of anti-lock and no scaling, and can achieve the effects of low pressure loss, low wear and tear, low power consumption, anti-corrosion and anti-clogging.
4. Automatic valve blowdown, anti-blocking and anti-rust technology: the valve switches automatically at regular intervals, which effectively utilizes the instantaneous impulse of water caused by pipeline pressure to realize automatic valve blowdown and avoid valve rust and scaling.
5. Fully sealed design: All lines are fully sealed with epoxy resin, and there are no exposed electrodes, so the sealing performance is good.
6. Anti-electromagnetic attack technology: When there is a strong electromagnetic attack from outside, the water meter will automatically close the valve.
