KM04-02
Used for household or residential units to measure, memorize and display the consumption of drinking cold water flowing through the pipeline. A new type of water meter using IC card technology to transfer water consumption data and settle transactions. It can realize automatic monitoring functions such as pre-payment, automatic charging, step charging, alarm warning, and data upload.
