FS2000L Flow Switch

Flow Switch Summary

The FS2000L flow switch inline type combines extraordinary responsiveness and accuracy with superior reliability in extreme process conditions. This product features an advanced non-intrusive sensor design constructed of 316L stainless steel and is available with 20 Ra or 10 Ra electropolish finishes that are suitable for high purity and sanitary environments. Inline sizes range from 0.50 to 2 inches for easy installation using male NPT, butt weld or sanitary flanges. FCI is the only thermal manufacturer providing temperature compensation to ensure set point accuracy for process temperatures that vary up to ± 100° F.

All FS2000 series flow and level switches are designed with proven thermal mass flow sensor technology in a rugged package that is easy to install and requires minimal maintenance.
