The Omron 61F-G3N Level Controller is a DIN rail-mounted, floatless level controller that uses conductive level detection to monitor liquid levels across up to three points. It provides a relay output and operates from 100 to 240 VAC, enabling automatic pump control to prevent overflow or dry-run in water treatment systems, boilers, cooling towers, pumping stations, and other industrial liquid-management processes. With adjustable sensitivity for different liquid conductivities, IP40 protection for panel installation, and a compact design, the 61F-G3N is commonly used for level monitoring and pump control, with common replacements including Omron 61F-G2N and 61F-D21T.
