Liquid Flow Switches What they do Detect liquid flow in piping and actuate an electrical switch to control pumps, valves, alarms, or controllers. Key benefits Protect pumps from dry running by stopping flow when it falls below a setpoint. Improve process safety and automation reliability with immediate flow status signals. Easy integration with standard control systems and wiring. Core features Function: switch output (normally open or normally closed); some variants offer an adjustable trip point for precise control. Compatibility: designed to work with common control panels and PLC inputs; suitable for a range of liquids within model specifications. Size and connection: available in multiple connection sizes to fit typical piping; compact form for tight installations. Materials and durability: housings and wetted parts designed for typical liquid applications; check model datasheet for exact materials and seals. Performance: fast response to flow changes; stable operation across operating ranges; reliable in continuous service. Configurations and installation Electrical outputs: normally open (NO), normally closed (NC), or both on select variants. Mounting and installation: inline installation with standard fittings; orientation options vary by model. Use scenarios Pump protection in cooling loops: detect insufficient flow and stop the pump to prevent damage. Irrigation or water treatment dosing: ensure continuous flow to dosing equipment and trigger alarms or stop dosing if flow stops. HVAC water circuits: verify flow in chilled or hot water systems and integrate with control logic to adjust pumps or alert operators. Why this product Provides clear, automatic flow status to support safe, efficient operation. Reduces downtime and equipment wear through early detection of flow issues. Flexible options to match piping size, liquids, and control needs.
