Barksdale BFS10-N Adjustable Water Flow Switch

The Barksdale BFS-10-N Adjustable Water Flow Switch is a compact inline device that provides a normally open contact that changes state when water flow crosses its adjustable threshold, enabling straightforward integration with pumps and control systems. It features a G1/4" process connection and a switch output rated for 200 VAC at 1 A, suitable for standard electrical controls in water systems. The water-flow version supports two primary ranges for switching: a low-flow band around 0.005–0.06 L/min and a higher-flow band around 60–150 L/min, with the setpoint adjustable within these ranges to fit specific applications such as pump protection, cooling-loop monitoring, and process-line flow verification.
