FS-930 Series Flow Switch, 0-1.0 GPM Flow, 1/4" NPT Female
A unique, patented piston design assures accuracy within 20% over a full range of viscosities - from 40 to 1000 SSU. 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-ups. The switch compensates for viscosity changes automatically. Each unit is factory preset, using 300 SSU oil for actuation at specified flow rates.
