Minor-caliber Remote Water Meter（Plastic）

Product ID.：WL601SC-P

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

This water meter realizes remote wireless meter reading via LoRaWAN(NB-IoT, Wireless M-Bus, optional) communication technology, avoiding the trouble of traditional wired water meter wiring. The water meter complies with LoRaWAN(NB-IoT, Wireless M-Bus, optional) communication protocol standard. Under normal use environment, the battery (ER18505) life can reach more than 5 years. Battery replacement is simple and reliable, and installation and maintenance costs are low. The body is made of environmentally friendly plastic, light and durable. Users can realize remote management and maintenance of water meters through the SES(smart energy system).
