Harwil Q-12N/Q12CR Flow Switch

Harwil^® type Q-12N & Q-12CR switches are provided with three factory adjustable parameters – paddle area, length, & stiffness – which provide performance flexibility to meet a multitude of applications. A positive stop eliminates fatigue effects of turbulence, vibration, and flow surge on flow detecting element. They have a very low pressure drop, typically less than 1.0psig at normal flow rate. Their small size and low profile provides easy mounting in crowded installations.
