KM04-05
Used for household or residential units to measure, memorize and display the consumption of drinking cold water flowing through the pipeline. The biggest highlight of the water meter is the periodic reporting function, which is carried out every half hour to check the user's water consumption. The data is stored and reported once a day. The reported data is a set of water consumption data within 24 hours. In addition, you can set the reporting period as required.
