FS2000 Flow Switch NuTec®
Flow Switch SummaryThe FS2000 flow switch provides an economical solution for alarm and limit trip switch applications in process and plant installations. FCI's unique thermal dispersion technology provides exceptionally accurate, reliable, and repeatable flow and no flow detection. The FS2000 flow switches have no moving parts to maintain or foul to ensure long service life and reduce routine maintenance costs. These insertion type flow switches provide a fast response, highly repeatable trip point with a heavy duty SDPT 6A relay contact. The FS2000 is for use in liquid or gas flow applications and is rated for installation in hazardous locations.
