The FLS compact Ultra Low Flow sensors ULF have been for use with every kind of aggressive and solid-free liquids. The sensor can be fixed to flexible or rigid pipes via 1/4” GAS threaded process connections. The paddlewheel sensor produces a frequency output proportional to the flow velocity that can be easily transmitted and processed. The ULF sensor offers two different flow ranges starting from 1.5 or 6 l/h (0.0066 or 0.0264 gpm). The construction materials, POM or ECTFE (Halar®), provide high strength and chemical resistance.
