Toro TFS-100 1" Flow Sensor — 1" PVC Socket Tee, 2-Wire Pulse Output

The Toro TFS-100 is a durable 1" flow sensor with an integrated PVC socket tee, engineered for irrigation monitoring, leak detection and accurate water-use tracking. Its simple impeller design and potted electronics make it suitable for valve box or buried installation while offering reliable pulse output for controller integration.

• Optimized flow range: Recommended 5–50 GPM operating range for the 1" TFS-100 model, accurate enough for water-use tracking and leak detection.
• Pulse output: 2-wire unscaled pulse output (pulse width ~5 ms) compatible with frequency-output controllers for alarm and monitoring functions.
• Construction: PVC socket tee with potted PPS sensor housing, 300SST impeller, tungsten-carbide shaft and UHMWPE bearing for long service life.
• Pressure & temperature: Pressure rating up to 150 PSI for 1" sizes and temperature rating suitable for typical irrigation environments (see product manual for limits).
• Installation & serviceability: Sensor is pre-installed in the tee with a removable design that allows replacement without removing the tee from the line.
• Compatibility & accuracy: Works with Toro controllers such as TMC-424, TIS-PRO, Sentinel and SitePro, and with other controllers requiring frequency output; typical accuracy is ±3–5% for 1" sizes.

Use the TFS-100 to add flow-based monitoring and alarms to irrigation systems, reduce water waste, and detect leaks early.
