Automatic Meter Reading and Remote Meter Reading
Automatic Meter Reading (AMR) and Remote Meter Reading (RMR) elaborate several systems which permit meters to be checked without the requires to send a meter reader out. This could be efficiently achieved using off-site metering, which is an electronic meter is placed at the junction point whereas all the connections originate and inaccessible to the end-user and it relays the readings through the AMR technology to the utility. Remote metering enables online metering of energy consumption. It is particularly meaningful for high value consumers where accuracy of billing and delays in time taken for meter reading are significant. Monitoring of consumption patterns to detect theft/ tampering of meters is possible with these types of meters.
The remote metering unit might be the RTU (Receiving Transmitting Unit), that receives the pulses generated through the electronic meters and is connected to the Central PC (Personal Computer) Station by a communication system that could be PLC (Programmable Logic Control), public switched telephone network, radio, etc.
