The Toro TFS-075 is a reliable 3/4 inch flow sensor preinstalled in a plastic tee, engineered for irrigation monitoring and leak detection. Its simple impeller design and potted electronics make it suitable for buried valve-box installation while providing repeatable pulse output for accurate water usage tracking.

  • Suggested operating range: 2.7–28 GPM (size sensors by expected flow, not pipe diameter).
  • Output & signal: 2‑wire, unscaled pulse output (pulse width ~5 ms ±25%); frequency range ~3.2–200 Hz.
  • Construction & materials: potted PPS sensor housing with 300SST impeller (½–1" models), tungsten-carbide shaft and UHMWPE bearing; tee is socket-end Schedule 40 PVC for ¾" installations.
  • Pressure & temperature: rated up to 150 PSI for ½, ¾ and 1 inch models; temperature rating up to 140°F (consult manufacturer for extremes).
  • Installation features: sensor preinstalled in tee with removable insert for service without removing tee; color-coded 18 AWG direct-burial leads included.
  • Compatibility: Designed for use with Toro controllers (TMC-424, TIS-360/480, Sentinel, SitePro) and any controller that accepts frequency/pulse output flow sensors.

Use the TFS-075 to monitor flow in residential, commercial, and municipal irrigation systems. Size the sensor to the expected flow, mount the tee in a straight run, and connect the two-wire pulse lead to a compatible controller or flow monitoring module. For signal runs over long distances the internal preamplifier supports dependable pulses up to approximately 2000 feet; for warranty details and complete specifications consult Toro documentation or contact the manufacturer.
