Why Electromag Meters Are Transforming Residential Water Metering

Residential water metering is evolving as utilities confront revenue loss, aging infrastructure, and the limitations of traditional measurement technologies. Mechanical meters degrade over time and often miss low-flow usage, while ultrasonic meters—despite having no moving parts—can struggle with sampling gaps and signal interference. Electromagnetic metering is emerging as a compelling alternative, offering a fundamentally different approach to accuracy and reliability. By continuously measuring flow across the entire pipe, electromag meters provide a clearer picture of water use under all flow conditions, including those that typically go unnoticed. Advances in engineering have made it possible to deploy this technology at the residential scale, combining long battery life, compact design, and robust security features. Beyond billing accuracy, these meters open the door to richer operational insight, better customer engagement, and stronger protection against non-revenue water. As utilities plan long-term investments expected to last decades, electromag meters are reshaping expectations for performance, durability, and data quality at the residential endpoint.
