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 leads to efficient management of the network and better customer experience.In this video, we are covering the evolution and system requirements of the water meter and the parameters that can affect their performances. Additionally, we will introduce the predictive maintenance concept for smart meters.
