Smart GPRS Data Concentrator Remotely Meter Reading For AMR AMI Metering System
CA08 GPRS data concentrator is dedicated to smart metering application and designed as a gateway between metering devices and AMR/AMI system, CA08 creates two ways communication from metering points to AMR/AMI system, performs task setting, data collection, data transmission and data storage, meter management, GPRS information task execution and RF network management.
CA08 data concentrator utilize efficiently RS485, RF-LORA media for downlike communication to smart meters and GPRS, 3G, DSL and fiber optic for uplink communication.
In the places where many meters are situated within1 kilometer radiance, mini-concentrator is the most economic and reliable means of managing various meters.
