KM04-04
Used for household or residential units to measure, memorize and display the consumption of drinking cold water flowing through the pipeline. By using photoelectric direct reading module to realize electronic sampling and upload the data to the base meter counting device, the metering data of the water meter can be accurately read in real time, and the metering data can be sent to various intelligent meter reading systems through wired transmission.
