A wide \u003cstrong\u003e0.1 to 6 m\/s (0.3 to 20 ft\/s)\u003c\/strong\u003e range covers low-flow drip headers up to high-volume mains. The 66:1 turndown ratio means one sensor handles morning irrigation and night recirculation on the same line.\u003c\/p\u003e\n\u003ch2\u003ePaddlewheel Flow Sensor with Open-Collector Output for PLC and Growlink\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe open-collector sinking output runs up to \u003cstrong\u003e10 mA\u003c\/strong\u003e.

Pressure rating sits at 180 psi at 68°F and derates to 25 psi at 185°F, with operating temperatures cleared from 0 to 185°F. The sensor lands in a standard 1.5 in NPT or compatible installation saddle.
