AMR vs AMI

摘要

The advent of automatic meter reading (AMR) came about in the mid-'80s, and more prominently in the early 1990s as an automated way to collect basic meter-reading data. The term and technology behind advanced metering infrastructure (AMI) began showing itself around 2005, evolving from the foundations of AMR. As not uncommon in this industry, we often hold on to the label that came first or use two terms interchangeably, even if the actual meaning or definition is slighdy different. All AMI systems contain AMR functionality (although it's not the core of its purpose), but all AMR systems are not AMI systems.
