Solution Details

Policy Background for Secondary Water Supply Monitoring

Secondary water supply safety has become a critical component of urban public safety worldwide. Regulatory requirements increasingly mandate intelligent monitoring for pump stations serving high-rise buildings, with real-time water quality monitoring at distribution endpoints.

Technical Highlights: Full-Element Sensing and Intelligent Constant Pressure Control

Ecolor's secondary water supply monitoring system uses Hero V9 RTU as the core controller, integrating LGF electromagnetic flowmeters, pressure transmitters, residual chlorine analyzers, and level meters. PID+feedforward compound control algorithms achieve constant pressure accuracy of ±0.02MPa. VFD energy-saving mode dynamically adjusts pump speed and running units based on real-time demand, achieving 30%+ energy savings.
