Battery and System Health Monitoring of Battery Powered Smart Flow Meters Reference Design

1 января 2018

This reference design showcases innovative solutions for battery and system health monitoring of battery-powered Smart Flow Meters. The battery monitoring subsystem provides highly accurate energy measurement and State of Health(SOH) projections which forecast battery lifetime. The system monitoring subsystem protects against over current conditions which can dramatically reduce battery life. The techniques demonstrated here can help extend the effective life of battery-powered meters and optimize total cost of ownership for utility operators.
