Gems Flow switches

FS-600 Series ¨C No Moving Part, Thermal Dispersion Flow Switch Flow Rate Settings: 0.1 GPM to 11 GPM (0.5 LPM to 41 LPM) Port Size: 1/2 to 1-1/2 (NPT or G thread) Setting Type: Fixed The FS-600 series uses proven thermal dispersion technology to provide a robust no moving part low switch even without iltration. The solid state sensor is compatible with both conductive and non-conductive luids. Suitable for luids 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 and can handle a wide range of low rates. No moving parts means years of reliable service.
