This inline water flow sensor uses a Hall effect sensor to monitor liquid flow in pipelines. It is powered by DC voltage in the range of 5 to 18 V and is designed for installation with a 3/4 inch connection. The device is supplied as a single piece. Key benefits Enables accurate monitoring of water flow for control and automation projects Simple integration with microcontrollers and controllers (such as Arduino, Raspberry Pi) through its pulse output Compact inline design for easy installation in tight spaces Low power operation within the 5–18 V DC range Provides realtime feedback to help prevent waste, leaks, or insufficient flow Key attributes Functionality: Hall effect water flow sensor / flowmeter Output: Pulse signal suitable for counting to determine flow rate (exact output type is consistent with common Hall effect flow sensors) Compatibility: Operates on DC power from 5 to 18 V Size / connection: 3/4 inch connection Package: 1 piece Material: Not specified in the listing Performance: Designed for inline flow measurement in waterbased liquids; suitable for integration into automation and monitoring systems Typical use cases Home irrigation and garden automation: monitor and regulate watering based on actual water flow to improve efficiency and conserve water Aquarium or hydroponics systems: track circulating water flow to ensure proper filtration and nutrient delivery DIY cooling or beverage equipment: monitor flow in liquid circuits such as water cooling loops for electronics or smallscale beverage processing, enabling flowbased control and safety alerts Installation and integration notes Install inline with the 3/4 inch pipe connection Connect to a DC power source within the 5–18 V range Interface the sensor's output with a microcontroller or data logger to count the pulses and calculate flow rate Verify flow with the system in a safe state before full operation Package contents 1 x water flow sensor (3/4 inch) This description reflects the product's stated features and typical use scenarios while maintaining a professional, clear tone suitable for informed decisions.
