Project Description

Flow Sensors

FEATURES

  • Threaded retaining nut makes it easier to service in a valve box
  • Molded mounting tee provides consistent measurements and improved performance
  • Four bladed lightweight impeller is sensitive enough to measure lower flow rates
  • Smart electronics capable of better signal filtering
  • Affordable enough to install on nearly all new and old systems
