FS-380 Series – Compact Flow Switch
for High Inline Pressures
Flow Rate Settings: 0.15 GPM to 2.00 GPM
Port Size: Multiple
Primary Construction Material: Brass or Stainless Steel
Setting Type: Fixed
These rugged inline flow switches require 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.
