FS-380 Series – Compact Flow Switch
for High Inline Pressures
Flow Rate Settings: 0.15 GPM to 2.00 GPM
Port Size: 3/8˝ NPT Male
Primary Construction Material: Brass or Stainless Steel
Setting Type: Fixed
These rugged inline flow switches use 100 micron filtration and are less susceptible
to clogging than other high-pressure inline flow switches. The one-piece magnetic
PPS composite piston makes the FS-380 ideal for high-pressure applications such
as industrial cleaning equipment. The FS-380 is also an excellent choice for semicon
cooling applications where simple design and reliable operation are required.
