The Flowline LO10 Switch Tek Optic Leak Detection Switch provides reliable leak detection in and around secondary containment sumps, tanks and piping systems with a 1A relay output. Media examples include sulfuric acid, water and diesel. The submersible polypropylene or PFA liquid leak detection sensor is mounted through the wall or within the interstitial space.

Additional benefits and features of the Flowline LO10 Switch Tek Optic Leak Detection Switch include: Submersible polypropylene or PFATeflon® sensor and cable for corrosive liquids; 60VA relay selectable NO or NC via power supply wiring polarity; Fail-safe leak sensor inverts wet to alert user for maintenance; Ideal for detecting leaks in secondary containment tanks and pipes; Switch fail-safe is "wet" preventing a switch from failing undetected; Useful in many corrosive liquids; Requires small amount of liquid to detect leak.
