LoRa Wireless Meter Reading Solution

I. System Overview

The HAC-ML (LoRa) meter reading system is an overall solution based on the LoRa technology for low-power smart remote meter reading applications. The solution consists of a meter reading management platform, a concentrator, a near-end maintenance handheld RHU and a meter reading module.

The system functions cover acquisition and measurement, two-way communication, meter reading control valve and near-end maintenance etc to meet the needs of remote meter reading applications.
