What is AMS, AMR & AMI?

Posted by Ingar Evjen Jan 4, 2017 9:49:22 AM

What is AMS, AMR and AMI?.pngYou may have heard about AMS, AMR, and AMI while reading up on smart meters. But the chances are, you’re probably clueless about what they mean. Don’t worry—you’re not alone. To make things a little simpler, we've put together a short guide to those confusing acronyms.

AMS (Advanced Metering System)

Also known as a Smart Metering System, AMS is a new type of gas and electricity meter that can digitally send meter readings to your energy supplier. It’s at the heart of the development of a SmartGrid and has the potential to save homes and businesses an impressive amount of money in the long run.


Now for the nitty-gritty. AMS is effectively an architecture for automated, two-way communication between a smart utility meter with an IP address and a utility company. Using a secure national information network, the meter automatically sends real-time data to your energy supplier. This information is then used to help customers make informed choices about energy usage, while also making it easier to switch suppliers.


NOTE: It’s also worth bearing in mind that in Norway AMS is used to describe Automatic Meter reading System.


AMR (Automated Meter Reading)

Automated Meter Reading is the technology responsible for collecting all sorts of data from your meters, whether it’s real-time information about consumption or diagnostic data. Once collected, the information is transferred to a central database for billing, troubleshooting and analyzing.


This technology not only saves you and your utility company the time and expense of checking the meter, but it also ensures accurate results. So no more staggering bills based on estimated usage.


This real-time data combined with more in-depth analysis gives you far more control over the consumption of electricity, water, and gas. Good news for those looking for a competitive deal from energy providers.



AMI (Advanced Meter Infrastructure)

If AMS and AMR are the building blocks of the SmartGrid, then AMI makes up the foundations. Advanced Metering Infrastructure is responsible for connecting the dots between the customer and the service provider.


So what exactly does it do? AMI is an integrated system that measures, collects and analyzes energy usage by communicating with metering devices, such as electricity, gas and water meters.


While they sound very similar to AMRs, AMI enables two-way communication between utilities and customers—something that AMRs are unable to do. AMI technology can also obtain data on power usage in homes and businesses, remotely switch the power supply on and off and measure power demand volumes in near real time.
