Gems FS-500 Series [170234] Flow Switch 24in 22 AWG Wire 2.50 gpm

TheThe Gems FS-500 series flow switches offer low cost flow monitoring with a variety of switch actuation points and low pressure drop. All wetted parts of the FS-500 series are polypropylene or stainless steel, making this switch ideal for a wide range of chemical and temperature requirements. The materials are also NSF or FDA approved for potable water treatment applications including chlorinators, purifiers and heaters. The FS-500 is ideal for equipment cooling including welders, lasers, etc. A J-box version with a 5 amp relay is also available for direct control of higher electrical loads, such as chlorinator pumps.

The FS-500 series has a 3/4" NPT process connection and flow settings ranging from 0.25 to 5.0 gpm. The simple and reliable design is suitable for operating temperatures from 0 to 212°F and line pressures up to 100 psig at 70°F. The FS-500 series utilizes a SPST switch.

Applications for the Gems FS-500 Series flow switch:

• Protect Bearings or Gears: oil separators, fuel systems, pumps, compressors, presses
• Electronics or Machinery: heat exchangers, semiconductor manufacturing equipment, induction furnaces, radio transmitters
• Process Systems: water filtration and reverse osmosis, chlorinators, de-icers, sterilizers, evaporators
