The Proteus Industries FS115 is a 100 Series fluid flow switch combining a paddlewheel/Hall-Effect sensor body with an integrated electronic control module (PCB 200075 Rev C). It monitors liquid flow and trips an internal SPDT relay when flow drops below the adjustable set point — preset here at 3.0 GPM — making it a compact solution for coolant flow monitoring and machine protection. Ports are 1/2″ NPT (IN and OUT labeled), rated to 250 PSI, and compatible with 24 VDC or 120 VAC power; trip point is field-adjustable via the recessed 20-turn potentiometer visible on the PCB. Guaranteed functional.
