Minor-caliber Smart Water Meter

Product ID.：WL601SC

Communication mode：LoRaWAN/NB-IoT/Wireless M-Bus

This water meter realizes remote wireless meter reading via LoRaWAN or NB-IoT or Wireless M-Bus(optional), avoiding the trouble of traditional wired water meter wiring. The water meter complies with LoRaWAN or NB-IoT or Wireless M-Bus protocol standards(optional) , and has the advantages of low power consumption, long battery life, simple installation and so on. The water meter supports battery replacement, which is convenient and quick to operate and reduces installation and maintenance costs. The SES(smart energy system) enables remote management and maintenance of water meters, real-time water consumption data reporting and remote valve control through two-way communication, which helps water companies to improve operating efficiency, reduce non-profit water use, effectively use water resources, and protect the environment. While realizing the intelligent management of the water company, the customer experience can be improved through services such as online payment, settlement, water management, and maintenance reporting.
