1/2' / 3/4' DC 518V Water Flow Sensor Flowmeter Hall Control Liquid Switch (3/4', 0.75 Inch) A compact inline flow sensor designed to monitor water flow and provide a reliable electrical switching signal using Halleffect control. Available in 1/2' and 3/4' (0.75 inch) sizes and powered by DC 5–18V, this flowmeter is suitable for applications that require simple, dependable flow detection and control. Key benefits Dependable flow detection: Halleffect control provides consistent switching behavior for flow monitoring and automation. Wide operating voltage: Works from DC 5V up to 18V, making it compatible with a broad range of power supplies and control systems. Size options for common plumbing: Available in 1/2' and 3/4' sizes to fit typical residential and light commercial piping. Simple integration: Designed as an inline liquid switch / flowmeter to easily add flow feedback to pumps, controllers, or alarms. Prevents damage and waste: Use it to detect noflow, lowflow, or excess flow conditions and protect equipment or conserve water. Key attributes Functionality: Water flow sensor and flowmeter that acts as a Halleffect liquid switch. Voltage: DC 5–18V operating range. Sizes: 1/2' and 3/4' (0.75 inch) options to match common pipe diameters. Use: Intended for water flow monitoring and liquid switching applications. Form factor: Inline flow sensor for straightforward installation inline with piping. Practical applications and use cases Pump protection and control: Install on the pump discharge or suction line to detect flow presence. Use the sensor signal to shut down a pump on dryrun or to trigger alarms for flow loss. Water systems and filtration: Monitor flow through filtration units, water dispensers, or RO systems to activate solenoids, display flow status, or log usage. Irrigation and process automation: Integrate with controllers to verify irrigation lines are operating, detect blockages, or confirm delivery of liquids in automated processes. What customers should know This unit is designed specifically as a water flow sensor / liquid switch with Halleffect control and requires DC 5–18V for operation. Choose the correct size (1/2' or 3/4') for your piping to ensure a proper fit and reliable performance. Intended for inline installation to provide an electrical signal tied to liquid flow; confirm compatibility with your control electronics and mounting arrangement before installation.
