AIM's Automatic Meter Reader is an intelligent embedded device supporting GSM/GPRS/CDMA technologies. ARG18 reads data using proprietary/standard/internation protocolls from energy/water meters. The final output is sent to the data center in common data format (CDF) which is in compliance to the MIOS and other internationally accepted standards.

AMI's Automatic Meter Reader is indigenously desing and developed at its research and development center in Hyderabd. It is a proven, rugged, compact, scalable and cost effective product. AMI has extensively worked on DLMS,MODBUS, IEC, PACT, PROFIBUS and various and other international standard protocols. AIM has rich ecperience in emmbedded system based solutions addressing critical and real time applications.

  • Recommended Stabdard-RS-232 for 1 Meter
  • Recommended Stabdard-RS-485 up to 32 Meter
  • In Case of more than one meter, the meters can be connected to the RS-485 port and the AMR can read data from multiple meters of various makes and models using daisy chain method.
