  • Gems FS-550 Flow Switch

    Item Type Media Type Connection Size Technology
    Hazardous Location, Industrial, OEM Corrosive Chemicals, Viscous Liquid (Oils, Syrups, etc.), Water (Clean) or Similar Liquids 1 - 1 1/2 Paddle

    Gems® type FS-550 high pressure, metal paddle switches sense liquid flow in either direction to monitor flow/no-flow conditions. They are supplied in two paddle lengths. The paddle is trimmed during installation to permit switch actuation at the desired flow rate. As flow increases in a pipe, the paddle of the switch pivots to move out of the liquid path, producing less than 3psig of pressure drop regardless of pipe size.

  • Gems FS-600 Flow Switch

    Item Type Media Type Connection Size Technology
    Industrial, OEM Corrosive Chemicals, Viscous Liquid (Oils, Syrups, etc.), Water (Clean) or Similar Liquids, Water (Dirty) 1/8 - 3/4, 1 - 1 1/2 Thermal Dispersion

    Gems® type FS-600 switches use proven thermal dispersion technology to provide a robust no moving part flow switch even without filtration. The solid state sensor is compatible with both conductive and non-conductive fluids. It is suitable for fluids with particulates or slurries, and is immune to changes in media viscosity. The straight through switch is designed for a long life and can be mounted in any orientation to handle a wide range of flow rates. No moving parts means years of reliable service.

  • Gems FS-925 Flow Switch

    Item Type Media Type Connection Size Technology
    OEM Air/Gas, Corrosive Chemicals, Viscous Liquid (Oils, Syrups, etc.), Water (Clean) or Similar Liquids 1/8 - 3/4 Piston

    Gems® type FS-925 general purpose switches provide reliable and consistent performance with repeatability within 1%. They are factory preset for actuation at specified flow rates. They provide accurate detection of excessive or insufficient flow rates in such applications as: protecting against loss of fluid flow in hydraulic systems, assuring proper coolant flow in semiconductor processing equipment, monitoring high pressure lubrication systems, and ensuring proper air flow in water/waste systems.

    OEM Air/Gas, Corrosive Chemicals, Viscous Liquid (Oils, Syrups, etc.), Water (Clean) or Similar Liquids 1/8 - 3/4 Piston

    Gems® type FS-926 low flow switches provide reliable and consistent performance with repeatability within 1%. They are factory preset for actuation at specified flow rates. They provide accurate detection of excessive or insufficient flow rates in such applications as: protecting against loss of fluid flow in hydraulic systems, assuring proper coolant flow in semiconductor processing equipment, monitoring high pressure lubrication systems, and ensuring proper air flow in water/waste systems.

  • Gems FS-927 Flow Switch

    Item Type Media Type Connection Size Technology
    OEM Corrosive Chemicals, Viscous Liquid (Oils, Syrups, etc.), Water (Clean) or Similar Liquids 1/8 - 3/4 Piston

    Gems® type FS-927 compact switches measure only 1″ x 2¾” and are ideal for use where space is at a premium. Designed for use with water and oil, these switches are suitable for high volume OEM applications. They are ideal for coolant or lubricant flow monitoring in portable equipment and many other applications with space constraints.

  • Gems FS-930 Flow Switch

    Item Type Media Type Connection Size Technology
    Hazardous Location, OEM Corrosive Chemicals, Viscous Liquid (Oils, Syrups, etc.), Water (Clean) or Similar Liquids 1/8 - 3/4 Piston

    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.
