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, powerline carrier communication (PLCC), Radio frequency CATV etc.
 Automatic Meter Reading (AMR) is a telephone-based, calling outbound system, for utility control and reliable, low-cost meter reading.
 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
What’s AMR
 AMR brings significant benefits to the customer by providing increased meter-reading accuracy, fewer estimated bills, rapid response to read requests, automatic leak detection and billing options and provids detailed usage information about individual sites, which allows the utility to offer variable rates and encourage price-responsive behavior among customers.
 AMR improves operational management by providing just-in-time meter replacement, tamper detection, remote access, and automatic scheduling of meter reading. In short, AMR will optimize cost savings and maximize efficiency.
Rf based Amr technology
Radio frequency(RF) network-
There are
 Two-way RF systems (wake up system)
 One-way RF systems(continuous broadcast system)
 Hybrid system(combination of one-way and two-way technologies) in use.
Two-way systems
 A radio transceiver normally sends a signal to a particular transmitter serial number, telling it to wake up from a resting state and transmit its data.
 The Meter attached transceiver and the reading transceiver both send and receive radio signals and data.
One-way systems
 The transmitter broadcasts readings continuously every few seconds. This means the reading device can be a receiver only, and the meter AMR device a transmitter only.
 Data goes one way, from the meter AMR transmitter to the meter reading receiver.
Hybrid systems
 It combines one-way and two-way technologies, using one-way communication for reading and two way communication for programming functions.
Description of 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.
 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.
 Radio frequency based AMR can take many forms. The more common one are Handheld, Mobile, and Fixed network.
Amr working
It comprises of two units-
• Transmitter unit-
The data is send from transmitter unit to receiver
unit via RF channel.
• Receiver unit-
Transmitted data is received by antenna situated
at the receiver unit.

Benefits of amr
 Reduced meter reading costs.
 Ability to access difficult-to-read meters.
 Improved customer service.
 Reduced percentage of estimated bills.
 Improved meter reader safety.
 Implementation of real-time pricing.
 Reduced read-to-bill time.
 Distribution automation.
Amr over conventional meter reading
 Obtain more easily initial and final meter readings for opening and closing accounts.
 Streamline high bill investigations.
 Help pinpoint system losses.
 Help detect theft of service.
 Enable more frequent readings with little incremental cost.
 Enable custom billing dates.
 Support customized rates (e.g. for large customers).
 Provide detailed consumption information to customers.
 Provide watchdog service, like leakage monitoring.
 Improve revenue forecasting by tying detailed consumption information to production data and expected billings.
 Reduce bill adjustments.
 Meters can be read even in case the homes are locked.
Amr functions and features
 Time of Use and Meter Reading
 Self-diagnostic and Status Reporting
 Networking and System Hierarchy
 Data Communication and Other Functions
 Compatibility with water and gas metering systems
 Use of Ethernet LAN/ Internet for Remote Meter Reading and Data Management.
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 meter tampering and illegal drawing of power (hooking/power pilfering).
 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 possible.
