The Model F3.00 rotor flow sensor is a simple, reliable device designed for use with any type of solid-free liquid.

The sensor is capable of measuring flows from 0.15 m/s (0.5 ft/s) producing a highly repeatable frequency output signal.

The extremely solid construction and established technology guarantee exceptional yields, with no or very little maintenance.

Dedicated electronics with push&pull output are available for safe connection to any type of instrument/PLC digital input.

Specially designed adapter family reduces installation time in all pipe materials and sizes, from DN15 to DN600 (0.5-24”).
