FS-400 Series –
General Purpose, 90° Flow Path
Flow Rate Settings: Fixed Version: 0.75 GPM to 10.0 GPM
Port Size: 3/4˝
Primary Construction Material: Bronze
Setting Type: Fixed or Adjustable
Provides accurate flow detection in water and oil with 1% repeatability. Flow settings
on the adjustable version can be easily changed without disassembly. A shuttle by-
pass vane inside the housing is controlled externally using an ordinary flat-blade
screwdriver. These switches are ruggedly constructed of non-corrosive materials and
resist shock and vibration. Suitable for triggering alarms on interlocking shutdown
circuitry when flow rate is improper to protect bearings, gears and cooling systems.
