◆ Instructions for use
This product is suitable for measuring hot water volume from 0 ℃ to 90 ℃. When using hot water, the user hands over the water fee to the management department, which writes the purchased water amount into the IC card. The user inputs the purchased water amount into the water meter on the IC card, and the water meter automatically opens the valve to supply water. During the user's water usage process, the microcomputer in the water meter automatically reduces the remaining water usage. After the purchased water is used up, 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 again to supply water.

Characteristics of lithium battery series non-contact IC card hot 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 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.
