Toro TFS-050 1/2-inch Flow Sensor, Plastic Tee, 1.2–12 GPM

The Toro TFS-050 is a 1/2-inch (15 mm) flow sensor with an integrated plastic tee designed for reliable irrigation monitoring and water-use tracking. Engineered for below-grade irrigation systems, it delivers repeatable pulse output and simple in-line installation for residential and commercial controllers.

• Suggested operating range: 1.2–12 GPM (4.5–45 L/min) for accurate low-flow detection and water-use reporting.
• Plastic tee design fits 1/2" (15 mm) pipe and suits common schedule 40 PVC installations for straightforward placement.
• 2-wire unscaled pulse output with internal preamplifier to support long cable runs and clear frequency signal to compatible controllers.
• Direct-burial 18 AWG solid copper leads (two conductors) provided for durable underground wiring and easy connection.
• Pressure and temperature ratings suitable for irrigation: 150 PSI for smaller sizes and rated for typical irrigation temperatures up to about 140°F (consult local codes for operating limits).
• Works with any controller or system that accepts frequency-output flow sensors, including standard Toro controllers for alarm and flow monitoring functions.

Includes installation and technical documents to assist with sizing and setup. Size the sensor by expected flow rate rather than pipe diameter to ensure the best accuracy. The TFS-050 is intended for monitoring and alarm detection—use the listed operating range for consistent performance and consult the included install guide for mounting, wiring, and controller setup.
