Flow Switch
Calibrated flow indicator with switched output specifically designed for use with water. Suitable for installation in any plane. Utilises the technique of differential pressure across a piston against a calibrated spring, with the flow rate read off a scale marked on the viewing window. The switch incorporates an AC magnetically operated reed switch output (minimum current of 50mA) which can be adjusted across the flow range to enable remote indication of max/min, and flow rate exceeded
