FlowX3 ULF

Ultra Low Flow Sensor

The compact ultra-low flow sensor type ULF is designed for use with every kind of aggressive and solid-free liquids.
The sensor can be fixed to flexible or rigid pipes via ¼” 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.
