KM01-03
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. High coverage, stable signal. The data acquisition part can use 1L bit measurement, and the uploaded data is highly accurate.
