Product Description:
LXSK-II non-contact IC card intelligent cold water meter
Adopting an integrated shell structure, compact and simple, beautiful and sturdy
Fully sealed design: All electronic circuit components are sealed with epoxy resin, with no external leakage electrodes and good sealing performance. Non contact RF card technology: The interaction of water meter data adopts non-contact RF card technology, electromagnetic triggering, ensuring the sealing of the water meter and improving the service life of the user card. Adopting imported ultra-low power microprocessors and zero power technology in the circuit, the service life of the internal battery is greatly improved, ensuring more than 8 years of use.
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 the valve's
Automatic drainage to avoid valve scaling, rust and other phenomena
Independent battery compartment design: convenient for property management to replace batteries without damaging the lead seal of the entire meter
Anti external electric and magnetic attack technology: When there is a strong electric or magnetic attack from the outside, the water meter will automatically close the valve
Remaining water level alarm prompt function: When the data in the table is reduced to the remaining water level, the valve will be automatically closed to remind the user, so as not to affect the user's water use due to insufficient water level
Data transfer function: When the water meter malfunctions, the engineering card can be used to transfer the faulty meter data to a new meter, thereby achieving the goal of not affecting the user's normal water use
Supporting the design of a single card for water, electricity, and heating, one user card can manage 4 water meters, which is very convenient for users with multiple meters in one household
