Product ID.：WL602SC
Communication mode：LoRaWAN/NB-IoT/Wireless M-Bus
This water meter uses LoRaWAN / NB-IoT / Wireless M-Bus technology to realize remote wireless meter reading and avoid the trouble of traditional wired water meter wiring. The water meter complies with LoRaWAN / NB-IoT / Wireless M-Bus communication protocol standards. Under normal use environment, the battery (ER18505) can serve more than 5 years and can be replaced easily, which helps to reduce the cost of installation and maintenance. The mechanical part and the electronic part can be separated independently, which can be flexibly used for on-site deployment. The built-in anti-shear mechanism can effectively monitor abnormal operations. Operators can use smart energy system to remotely manage and maintain water meters.
