Automatic meter reading (AMR) technology uses radio frequency networks to remotely collect utility meter readings, reducing the need for manual readings. AMR systems provide benefits to both electrical companies and customers by automating processes, enabling more precise billing based on actual usage, and detecting tampering. Common AMR technologies include handheld, mobile, and fixed network approaches. A typical AMR system uses a transmitter unit attached to the meter to send usage data via RF signals to a receiver unit, with the data then processed by a central computer system. While complex communication patterns and algorithms pose challenges, AMR allows for streamlined operations and its capabilities are growing to include additional functionalities like event monitoring.

2. What is AMR?
 Automatic meter reading
 This saves employee trips, and means that billing can
be based on actual consumption rather than on an
estimate based on previous consumption

3. Benefits Of AMR
Electrical company benefits:
• Smart automated processes instead of manual
work.
• Customized rates and billing dates.
Customer Benefits:
• Precise consumption information.
• Clear and accurate billing.

4. Different Types of AMR
Technologies
 Handheld
 Touch based
 Mobile
 Fixed network
 Radio frequency network

5. RF BASED AMR
 Originally AMR devices just collected meter readings electronically &
matched them with accounts.
 As technology has advanced, additional data could then be captured,
stored and transmitted to the main computer and often the metering
devices could be controlled remotely.

UNIT

7. WORKING OF TRANSMITTER
UNIT
 The data is send from the transmitter unit to the receiver
unit via RF channel.
 The pulse generator also having a AT89C2051
microcontroller.
 In transmitter unit we also use the four seven segment
display, which shows the reading of the meter.
 Each seven segment display has 7 LEDs

8. BLOCK DIGRAM OF RECEIVER
UNIT

9. WORKING OF RECEIVER
UNIT
 The transmitted data is received by the antenna situated at the
receiver unit.
 After receiving the signal the data is given to the pin no.8 of the
AM receiver.
 The output the AM receiver is given to the decoder HT12D.
 When the VT=1, the transistor is turn on and a high signal appear
at the collector terminal
 Due to which the LED which is connected to the collector
terminal is glow up and emit the light.

10. APPLICATIONS
 Wireless M-Bus
 Home control and industrial automation
 Street lighting (TinyMesh supporting up to 255 hops)

11. ADVANTAGES
 Smart automated processes instead of manual work
 Accurate information from the network load to optimise
maintenance and investments
 Customized rates and billing dates.
 Streamlined high bill investigations.
 Detection of tampering of Meters.

12. DISADVANTAGES
 Communication patterns between levels can be
complex.
 Algorithm complexity can be substantial.

13. FUTURE SCOPE
 Originally AMR devices just collected meter readings
electronically and matched them with accounts.
 This can include events alarms such as tamper, leak
detection, low battery, or reverse flow.
 Many AMR devices can also capture interval data, and log
meter events.

14. CONCLUSION
 Thus I have studied RF based automatic meter reading used
in different places. I got that this technology is very useful
in present and future demand.
 What was once a need for monthly data became a need for
daily and even hourly readings of the meters.
