In Automatic meter reading system project using GPRS, we implemented a GPRS Automatic Meter Reading System in order to enhance security for the electrical suppliers in controlling the unauthorized electrical power usage. Web services based GPRS automatic meter reading provides better solutions for the managements in meter reading of power consumptions accurately with no scope man made errors.
The architecture of web services based GPRS automatic meter reading system is designed using microprocessor, Remote Reading Units (RRU), telephone network i.e. Communication Front End (CFE). The meter readings were collected by the remote reading units and transferred to the communication front end systems at the control system and billing is done.
Need of Automatic meter reading systems:
- In order to prevent the bogus seals and tampering of seals.
- To reduce Meter tampering, meter tilting, meter interface.
- To control Meter bypassing.
- To limit the connection changing’s and Direct tapping from line.
Various Automatic meter reading techniques:
In AMR metering technologies we transmit data from transmitter end to receiver end by means of RF technology.
There are various AMR techniques like handheld computer, touch based AMR, Mobile or Drive-by meter reading, Fixed Network AMR, Radio frequency based AMR, Power Line Communication PLC type AMR system, and Wireless Fidelity (Wi-Fi) based AMR.

Benefits of AMR technologies:
When compared to conventional metering systems automatic metering systems are quite advantageous in terms of eliminating meter reading costs in manual operations, presenting interference free data transfer from the meter reading units to the billing units, and these are cost effective reliable and free from excess human involvement.
