Wireless Remote Wet Type Semi-Liquid Sealed Water Meter with Ball Valve

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 terminal collects water meter information, sends the data to the nearby base station through the built-in NB module, pushes the data directly to the IOT platform through the NB-Iot communication network, and finally the IOT platform pushes the data to the smart water application platform.
