  • Gems FS-930 Flow Switch

    Gems® type FS-930 oil flow switches compensate for viscosity change in fluids. Their unique, patented design assures accuracy witin 20% over a full range of viscosities – from 40 to 2000 SSU. They are ideal for use in applications where liquids of different viscosities are blended, or for use in lubrication systems where oil flow monitoring is critical at start-up. Each unit is factory preset using 300 SSU oil for actuation at specified flow rates and compensates for viscosity changes automatically.

  • Gems RFS Flow Switch

    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.

  • Harwil Q-1 Flow Switch

    Harwil® type Q-1 industrial flow switches are designed for extreme, long-term reliability. They detect and signal flow change and remain continuously adjustable while in operation. Six interchangeable orifices have 2:1 continuous switch adjustment. They are calibrated independent of line pressure and temperature, and maintain calibration limits when subjected to reasonable line hydraulic hammer or surge pulses. A DPDT model is available upon request.

  • Harwil Q-10N/Q-10VCR Flow Switch

    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.
