3. INTRODUCTION The meaning of AMR:  Automatic meter reading (AMR) is the collection of, at a remote central location, data from consumption meters located at customers’ premises via telecommunication links.  The meters could measure gas, water or electricity flow. These links could be Telephone lines, power line carrier communication (PLCC). www.engineersportal.in

4. INTRODUCTION(contd.)  With the use of AMR, the need of a person to visit the consumer’s site and record the readings of the meters is eliminated. This also prevents human errors in recording the reading www.engineersportal.in

Smart Metering and IT: An opportunity to Leapfrog PAST ELECTRO-MECHANICAL  Low Accuracy  Control – NIL  Communications - Expensive  Theft Detection – Poor CURRENT DIGITAL SOLID STATE  High Accuracy  Control – LIMITED  Communications – External through Retrofit  Theft Detection – Node only LEAPFROG NEXT GEN SMART METER & IT SYSTEM  Very High Accuracy  Control – FULL  Communications – Built in (on chip / PCB)  Theft Detection – High (Network level) www.engineersportal.in

6.  The key to the system is a device called an ERT(Encoder-Receiver-Transmitter).  This device is connected directly to a special electronic register on the meter.  When an ERT receives the signal, it checks the reading on the meter register, encodes it into a digital signal, and begins transmitting its identification number and the current reading.

10. CUSTOMER BENEFITS –  Precise consumption information –  Clear and accurate billing –  Automatic outage information and faster recovery –  Better and faster customer service –  eter  Reading is possible when home is locked. www.engineersportal.in

11. AMR Function & Features  Time of Use and Meter Reading  Self-diagnostic and Status Reporting  Data Communication and Other Functions  Compatibility with water and gas metering systems  Use of Internet for Remote Meter Reading and Data Management. www.engineersportal.in

12. Disadvantage of AMR System Circuit of AMR is very complicated. The installation of AMR system is more costly then of conventional system. AMR stop working when do not have power supply. www.engineersportal.in

13. CONCLUSION  Since automatic meter reading is all about “Reading a utility meter without the requirement for visual inspection of the meter”, it is indeed an easy and fail-safe method for monitoring consumption details of a customer.  Automatic Meter Reading can detect illegal drawing of power (hooking).  AMR as a way of improving customer service while reducing the cost of reading meters.  The Automatic Meter Reading system enables us to save millions of dollars every year in meter reading costs and also provide our customers with better information about water use, more accurate billings, and keep rates as low as we can. www.engineersportal.in
