KM01-06
This series of products are wireless remote water meters which separates the mechanic part from intelligent module completely, and upload the water consumption through NB\LORA Internet. The valve control meter can control the switch of the valve through the process of the meter reading platform. When the battery voltage is low, it will report to the meter reading platform to make an alarm. The current voltage of the battery is displayed on the meter reading platform to judge the battery usage.
