NB-IoT Split-Type Meter Reading Terminal

The NB-IoT Split-Type Meter Reading Terminal is a wireless data collection device designed for smart water, gas, and heat metering applications. It connects compatible mechanical meters to a remote AMR / AMI platform through NB-IoT communication, enabling utilities to collect meter readings, monitor abnormal conditions, and manage field devices more efficiently.

With split-type installation, low-power operation, infrared maintenance, IP68 protection, and long-term data storage, this terminal is suitable for retrofit projects where existing meters need to be upgraded for remote reading without replacing the complete meter body.
