KM01-20
This series of products are wireless remote water meters that the mechanic part from an intelligent module completely and upload the water consumption through LORA Internet.LoRa water meters leverage LoRa technology, a wireless communication protocol known for its long-range capabilities, low power consumption, and efficient data transmission. These meters are designed to remotely measure water consumption in residential, commercial, and industrial settings, providing accurate and real-time data insights to utility providers and consumers alike.
