Gems FS-930 Series Flow Switch

Gems^® FS-930 series flow switches compensate for viscosity change in fluids. Their unique, patented design assures accuracy from 40 to 2000 SSU (which is within 20% over a full range of viscosities). The FS-930 switches 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.
