MINI PADDLEWHEEL FLOW SENSOR – FLS F3.10

The simple and reliable paddle wheel technology has been moved into this mini flow sensor type FLSF3.10, designed for use with every kind of solid-free liquids. The sensor can measure flow from 0.25 m/s (0.8 ft/s)producing a frequency output signal highly repeatable. A rugged construction and a proven technology guarantee exceptional performances with little or no maintenance required. The very small dimension and a special design make it suitable for installation on FIP standard Tee-fittings from DN15 to DN40(0.5 to 1.5 in.).
