Installation
All NPT threads should be installed using a suitable thread sealant (Teflon
tape or Permatex “No more Leaks”). Sealant must be kept out of unit
during installation. Ten diameters of straight run piping are recommended
upstream and downstream of the flow sensor.
The FS-380 end fitting is threaded to the body at assembly and torqued to
25 Ft. Lbs. If disassembly from a system is required, it is advisable to hold
the end fitting hex with a wrench to prevent sensor disassembly. If the
sensor should become disassembled as a result of uninstalling, retorque
the end fitting to 25 Ft. Lbs.

Flow settings are based on a vertical
position (inlet port down), using water at
+70°F on increasing flow. Some variation
in set point actuation will occur in other
mounting orientations.
