Harwil - Model Q-10 -Flow Switch – 1 inch
Model Q-10 can be provided with three factory adjustable parameters which provide performance flexibility to meet a multitude of applications: Paddle Area. Paddle Length. Paddle Stiffness. Responds to fluid flow only, independent of line pressure and temperature. Max. flow may be five times normal flow.
Positive stop eliminates fatigue effects of turbulence, vibration and flow surge on flow detecting element.
Small size and low profile provides easy mounting in crowded installations.
Very low pressure drop - typically less than 1.0 psig at normal flow rate.
Quick response.
Available with NO, NC or SPDT Reed Switch
Switches 5VDC to 240VAC.
Switches resistive and light inductive loads.
Switch employs magnetic coupling.
