FS-925 Series Flow Switch

FS-925 Series Alloy Piston Type Flow Switch
  • Flow Rate Settings: Liquids - 0.1 GPM to 1.5 GPM; Air/Gases - see chart 
  • Port Size: 1/4" NPT 
  • Primary Construction Material: Brass or Stainless Steel
  • Setting Type: Fixed

This series of precision-calibrated switches provide reliable and consistent performance; repeatability is within 1%. FS-925 units are factory preset for actuation at specified flow rates.

These switches provide accurate detection of excessive or insufficient flow rates in such applications as: protecting against loss of fluid flow in hydraulic systems, assuring proper coolant flow in semiconductor processing equipment, monitoring high pressure lubrication systems, and ensuring proper air flow in water/waste systems.
