Data concentrator for RF Gas Meter and GasAMI Solutions Plug - in GPRS Module
The mini concentrator serves as a gateway between the head-end server system and the gas meters. It can handle upto 32 group metering points of over 200 pcs submeters. The mini DCU is a superb data collection device in villages, community blocks and multi-storey buildings. Its self-routering feature can establish a RF meshwork to manage the data exchange between the meter and the HES . The uplink to HES is available with GPRS or ethernet. The concentrator plays an important role in reducing the network burden, and backup the entire metering system structure.
In the places where many meters are situated within1 kilometer radiance, mini-concentrator is the most economic and reliable means of managing various meters.
