FS-200 Series Flow Switch - Alloy Switch

FS-200 Series Alloy Shuttle Type Flow Switch
  • Flow Rate Settings: 0.5 GPM to 100.0 GPM 
  • Port Size: 1" NPT to 2" NPT 
  • Primary Construction Material: Bronze or Stainless Steel 
  • Setting Type: Fixed

The FS-200 Series offers accurate flow detection, with 1% repeatability, over a broad range of flow settings and port sizes. Its durable construction delivers long-life reliability in either water or oil. Generous flow paths keep pressure drop low. These switches are ideal for detection of improper flow rates in high volume lubrication, cooling or process systems.

FS-200 Adjustable Series switches offer the same accuracy and are as rugged as those with fixed settings, but provide one additional feature: external adjustability. With these versatile switches your choice of flow settings is diverse within a given range. An ordinary, flat-blade screwdriver is all that's required for the actuation adjustment.
