SG Water Detection Probe Systems detect the presence of water in a filter-separator sump by utilizing a conductivity probe attached to the vessel and an intrinsically safe relay to control fuel flow by stopping a pump or closing a valve.


SG Style probes are designed to install directly into the sight glass connection of Facet’s® VF-21/22 housings. Just remove the snap ring and sight glass from the housing, then insert the SG Series probe assembly and reinstall the snap ring. No vessel modifications are required.
