IC Card Prepaid Water Meter

规格型号：

INTRODUCTION

The prepaid water meter is new type of smart water meter that uses modern microelectronic technology, modern sensing technology, and smart IC card technology to measure water consumption and conduct water data transmission and settlement transactions. It adopts a pre-paid method, which not only achieves reasonable charging, it will also automatically close the valve when the meter is in arrears.
