Over the last few years, the industry has been moving from mechanical to fully electronic meters. We have seen more and more functionalities such as metrology with ultrasonic technology, leak detection with audio patterns, communication with low power and long range radio being added to smart meters. These new functionalities allow utilities to deliver new services such as condition-based maintenance and remote monitoring of meters, which lead to efficient management of the network and better customer experience. During this video, we will discuss the primary battery characteristics and the parameters that can affect performance. Additionally, we will cover battery monitoring in smart meters.
