WeatherTRAK® FlowLink®

You’ll get reliable, real-time flow monitoring and alerting. FlowLink was designed specifically to avoid costly and disruptive trenching, giving you the ability to respond to catastrophic breaks and leaks, protect your property assets and manage water resources in a cost-effective way.

Reliable and affordable flow communication

  • Easy to install, use and maintain
  • Complete flow and master valve communication over existing field valve wire
  • Pre-paired field and control devices provide for easy field deployment and set-up
  • Easy-to-see LED indicators of device status and monitoring

Robust flow monitoring to protect against catastrophic events

  • Monitor five flow functions independently with flow readings and master valve control
  • Ability to test for catastrophic mainline breaks
  • Intelligent master valve management protects assets while avoiding unnecessary disruptions
  • Enhanced diagnostics & alerting

Intelligent flow analysis for true leak detection

  • Learned flow and station-level flow management for accurate alerts
  • Flexible global settings and ability to override individual settings—fine tune your monitoring
  • Leak detection engineered to find true leaks

Full flow visibility & reporting
