This stainless steel water flow sensor and control liquid switch is built for reliable flow detection and basic control in DCpowered systems. Available in four pipe sizes — 1/2' (0.5 inch), 3/4', 1', and 2' — and rated for DC 5–18V operation, it provides a durable, versatile option for monitoring and protecting water handling equipment. Key benefits Reliable flow detection: Detects the presence or absence of liquid flow so you can protect pumps, trigger alarms, or automate processes. Wide voltage compatibility: Works with DC 5–18V systems to integrate with common pumps, controllers, and automation boards. Durable construction: Stainless steel body improves corrosion resistance and mechanical strength for longer service life in water applications. Multiple size options: Choose the correct diameter (1/2', 3/4', 1', or 2') to match your piping and minimize plumbing adaptation. Main features and attributes Functionality: Acts as a liquid flow switch for monitoring or control purposes in fluid systems. Compatibility: Designed for DC systems using 5–18V. Can be used with controllers, relays, data loggers, and control circuits that accept a flow switch input. Sizes: Available in 1/2' (0.5 inch), 3/4', 1', and 2' to fit a range of pipe diameters. Material: Stainless steel construction for improved resistance to corrosion and wear in water service. Performance: Intended to provide consistent on/off flow detection to support equipment protection and automation. Suggested applications Pump protection: Use to detect flow and stop pumps on loss of flow to prevent dryrun damage and extend pump life. Water treatment and filtration: Monitor flow presence through filters, softeners, and treatment stages to trigger backwash cycles or maintenance alerts. Irrigation and irrigation control systems: Integrate with controllers to confirm water delivery, detect line blockages, or automate zone sequencing. Installation and use notes Select the sensor size that matches your pipe diameter to ensure proper fit and accurate detection. Intended for DCpowered control circuits in the 5–18V range; verify compatibility with your controller or relay input requirements. Stainless steel construction makes this sensor suitable for potable and nonpotable water applications where corrosion resistance is required. This water flow sensor provides a straightforward, durable solution for basic flow detection and liquid control in DC systems. Choose the appropriate pipe size and incorporate it into pump protection, automation, or monitoring setups to improve system reliability and safeguard equipment.
