Data Concentrator

Mainly used in the remote meter reading and data analytics and processing, the data concentrator achieves the functionalities including centralized meter reading of water meters, gas meters heat meters, thermostat, data remote transmission. The system can automatically switch between the collector mode and the data transfer mode.

Product Features:

-- Main control system uses of high performance ARM processor

-- Uses of high quality GPRS/DTU module, supports data network remote reading

-- Supports simultaneous online reading of water, gas,heat meters

-- Built-in CJ/T 188-2004 protocol

-- Supports functionalities such as regular AMR, manual meter reading, automatic analytics of protocol, offline working, supports local data storage, malfunction reports.

-- Supports real time timing automatic

-- Supports switch off of M-BUS line, lowers system functionality

-- Offers multiple types of second development interfaces, facilitating the incorporation into the 3rd meter reading management system

-- The system can automatically switches between collector mode and passthrough mode, under the  passthrough mode, you can view the measurement values from a certain slave meter in real time. 

-- Use of 160×160 LCD, facilitating viewing of the basic configuration information of the data concentrator.
