Smart Flow Meters for Sponge City Rainwater Harvesting | Rainwater Runoff Monitoring
Rainwater harvesting is shifting from construction-oriented to performance-driven. Smart flow meters including Doppler ultrasonic, partial-fill electromagnetic and open-channel types solve difficult metering problems of non-full gravity pipelines. It realizes real-time runoff monitoring, sediment blockage warning, retention tank intelligent scheduling and traceable rainwater reuse, providing reliable basic data for sponge city performance assessment.
