LXSK IC card prepaid water meter
1. Product overview IC card smart water meter is based on the original ordinary mechanical water meter with prepaid function. The
meter adopts microprocessor control technology for data acquisition and processing, LCD display, IC card medium
for data exchange, and micro-motor to control valve switch.
2. Product features ● The design service time of lithium battery power supply can reach to ≥6 years. ● One card and one key cannot be copied. ● When the battery is dead or replaced, the valve will be automatically closed, effectively preventing water theft.
When the battery is dead, the IC card will automatically open the valve when it contacts the sensing area of the
water meter, which will not affect the user's water use. ● The whole meter can be sprayed waterproof, that is, when the water meter shell is drenched with water (the time is not more than 24 hours), the work of the water meter will not be affected. ● When a magnetic object approaches the water meter, the water meter will automatically close the valve to prevent
the magnetic object from interfering with the metering of the water meter.
