FS-930 Series Flow Switch

FS-930 Series Alloy Piston Type Flow Switch
  • Flow Rate Settings: 0.1 GPM to 1.0 GPM
  • Port Size: 1/4" NPT 
  • Primary Construction Material: Brass 
  • Setting Type: Fixed

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. Switch compensates for viscosity changes automatically. Each unit is factory preset, using 300 SSU oil, for actuation at specified flow rates.
