DCU creates the necessary network infrastructure by linking several Gas/water metering units to the central utility server. It receives the data from the group MUI’s in the network and transfers all data to the configured Remote Data Server through GPRS Link. The data concentrator also synchronizes time and date of metering units to the central utility server and enables secure data transfer of user authentication. One DCU will be required for each Network Group, which can have up to 1024 metering units. DCU is an intelligent device with built-in 865MHz RF Tarang UT-20 module to acquire data from Gas Metering units with built-in GPRS to transmit data to the Data Acquisition Server Interfaced with Data Logger PC.
