1/2" Hall Effect Water Flow Sensor – DC 3.8–24V Inline Flow Meter
1/2" inline Hall-effect water flow sensor operating from DC 3.8–24V. Designed for low-pressure water systems, this compact plastic flow meter provides pulse output for accurate flow monitoring in dispensers, irrigation, and automation applications.
This 1/2" water flow sensor uses a Hall-effect detection mechanism to measure flow rate in low-pressure water systems. As water passes through the inline body, an internal turbine rotates. The integrated Hall sensor converts rotational speed into pulse signals proportional to flow rate.
Operating on a wide DC voltage range (3.8–24V), the sensor is suitable for integration with microcontrollers, PLCs, IoT devices, counters, and embedded control systems. It is commonly used in water dispensers, beverage machines, irrigation systems, and small pump circuits.
Constructed from durable plastic, the housing is corrosion-resistant and lightweight, making it ideal for clean water applications. The pulse output allows for total volume calculation, dosing control, and automated shut-off functions when connected to compatible control hardware.
