Harwil® type Q-16 switches are used to signal, start, or stop electronically operated equipment when flow or no-flow conditions occur. Harwil’s patented elastomeric sealing system is superior to the metal bellows that are subject to metal fatigue and corrosion. This seal system has been field-proven for over a decade.

Harwil® type Q-10N & Q-10VCR switches are provided with three factory adjustable parameters – paddle area, length, & stiffness – which provide performance flexibility to meet a multitude of applications. They respond to fluid flow only, independent of line pressure and temperature. A positive stop eliminates fatigue effects of turbulence, vibration, and flow surge on flow detecting element. Their small size and low profile provides easy mounting in crowded installations.

Gems® type FS-400 switches are general purpose, 90° flow path switches. They provide accurate flow detection in water and oil with 1% repeatability. Flow settings on the adjustable version can be easily changed without disassembly. A shuttle bypass vane inside the housing is controlled externally using an ordinary flat-blade screwdriver. These switches are ruggedly constructed of non-corrosive materials and resist shock and vibration. Suitable for triggering alarms on interlocking shutdown circuitry when flow rate is improper to protect bearings, gears, and cooling systems.

Gems® type RFS RotorFlow switches build an extra level of reliability and protection into your equipment. Once set to a desired actuation point, RotorFlow will switch to a “no-flow” condition should the rotor stop for any reason. Typical applications include semiconductor processing equipment, lasers, medical equipment, X-ray and other high power tubes, and robotic welding equipment.
