The IC card water meter is a new type of water meter that uses modern micro-electronics, modern sensor technology and intelligent IC card technology to measure the amount of water used and carry out water use data transmission and settlement transactions. It has the dual function of mechanical counting and electronic counting. Through electronic billing, the purpose of scientific water saving is achieved.
The prepaid IC card water meter system consists of a prepaid water meter, an IC card, a card reader and management software.
Base surface material: Brass/Stainless steel/Iron/Plastic/Nylon etc.
Applicable scene: garden, housing, commercial, general household, residential building, apartment, municipality, household potable. etc.
Technical data conform to international standard ISO 4064.
Low-power performance design, battery life up to 8 years.
Accuracy: Class B
Bi-directional transmission of water information through IC card to realize prepayment function.
Low power microcontroller technology to realize step charging function.
Fully sealed design, waterproof, leak proof and attack proof.
Regularly self-cleaning, to avoid scaling and rust of the valve.
When the remaining water volume is zero or the power supply fails, the valve will be automatically closed.
When the water volume exceeds the limit, the battery power is insufficient or the battery is replaced, the valve will be automatically closed and alarm triggered.
In case of external magnetic or strong electric attack, the valve will be closed automatically and the attack information will be recorded automatically.
Advantage of the prepaid water software
Language display and currency unit display can be customized, ODM/OEM is realizable.
The data will be saved automatically after exiting the system.
Easy to query consumption records.
Invoice printing, providing payment voucher to users in the most common form in the local market.
