IC card prepaid water meter

Product features
Ultra long standby life: Powered by lithium batteries, designed for a service life of ≥ 10 years;
Ultra low power consumption: static power consumption ≤ 10uA, annual power consumption ≤ 120mA;
Low pressure valve closing: When the current is ≤ 2.7v, the water meter automatically closes the valve;
Anti magnetic attack: When a magnetic object approaches, the water meter automatically closes the valve;
Maximum protection level: The protection level reaches and is superior to IP68;
Strong confidentiality: logical encryption, one table, one card, non cracked and non replicable;
Power off and valve closing: When the water meter circuit is cut off by a strong attack, the water meter will instantly release a large amount of current from the built-in capacitor and immediately close the valve.
