The Weathermatic SLFSI-T PVC tee-mounted flow sensor delivers reliable, serviceable flow measurement for irrigation systems that use SmartLink Flow. Designed to wire directly to the SmartLink Flow Aircard, the SLFSI-T provides digital pulse output for leak detection, zone-level monitoring, and automatic shutdown when predefined flow limits are exceeded.

  • Exact compatibility: Works with SmartLink Flow Aircard for web-based flow management and alerts.
  • Proven performance: 0.25 to 15 FPS flow range; tested to 240 PSI maximum working pressure.
  • Serviceable design: Threaded retaining nut and removable electronics housing allow in-field servicing without special tools.
  • Durable materials: Rigid PVC tee body, HDPE four-blade impeller, tungsten-carbide shaft, and Buna-N O-ring for long life.
  • Installation guidance: Requires minimum 10 diameters upstream and 5 diameters downstream for accurate measurement; housing needs ~4 inches clearance for removal.
  • Electrical: Two #18 AWG direct burial leads, 48-inch length; signal can travel up to 2000 feet with proper twisted-shielded cable.

Available in 1", 1-1/2", and 2" slip-type tee models (SLFSI-T10, SLFSI-T15, SLFSI-T20). The SLFSI-T is ideal for new installations and retrofits where dependable flow monitoring, early leak detection, and straightforward maintenance are required.
