Adopting mature Hall electromagnetic induction sensing technology, this water meter accurately captures real-time water flow rate and cumulative water volume, solving the pain points of inaccurate metering and poor environmental adaptability of traditional irrigation flow equipment. Designed for long-term outdoor and field operation, it features dustproof, waterproof, anti-corrosion and anti-clogging properties. As a professional sensor manufacturer, we provide both standard mass-produced products and personalized customized services to match different irrigation pipeline specifications, intelligent irrigation systems and diversified farmland garden management needs, delivering reliable flow monitoring solutions for modern precision irrigation.
Product Features
Excellent Outdoor Environmental Adaptability
Tailored for agricultural and garden harsh working conditions, the meter supports stable operation in variable temperature, humid, dusty and outdoor open-air environments. It resists sun exposure, rain erosion and low-temperature frost, avoiding performance attenuation or failure caused by complex outdoor factors, ensuring continuous and effective flow monitoring throughout the four seasons.
Anti-Clogging & Low Water Pressure Start
Optimized wide-flow channel and low-resistance impeller structure effectively prevent blockage from sediment, fine impurities and algae in irrigation water. It achieves sensitive start-up under low water pressure, accurately capturing micro-flow water volume in trickle irrigation and drip irrigation scenarios, with no missing measurement or inaccurate counting.
High Precision & Stable Long-Term Metering
Equipped with high-sensitivity Hall effect sensing elements, the product converts impeller rotation into standard pulse signals stably. It features low zero drift and good repeatability, with accurate metering for long-term continuous irrigation work. It effectively avoids data deviation caused by frequent water flow fluctuation in farmland irrigation.
Durable & Low Maintenance Cost
The whole machine adopts high-strength anti-corrosion engineering materials and wear-resistant rotating components, with strong pressure resistance and aging resistance. It has a long service life in field irrigation systems, no frequent replacement and disassembly maintenance, greatly reducing the daily operation and maintenance cost of agricultural irrigation equipment.
Working Principle
The FH-502 Hall Effect Sensor Water Meter operates based on the physical Hall effect principle. When irrigation water flows through the internal flow channel, the water pressure pushes the built-in magnetic impeller to rotate synchronously. The rotating magnet changes the surrounding magnetic field periodically, and the built-in Hall sensor captures real-time magnetic field changes and converts them into continuous standard digital pulse signals. The pulse frequency is linearly proportional to the water flow speed and flow volume. The matched intelligent control system or controller calculates real-time instantaneous flow and cumulative water consumption by counting pulse signals. The optimized flow channel structure stabilizes water flow and reduces turbulent flow interference, ensuring the accuracy and stability of signal acquisition, realizing automatic and precise metering of agricultural irrigation water volume.

Application Fields
The FH-502 Hall Effect Sensor Water Meter is specially developed for agricultural and garden irrigation scenarios, widely covering various precision irrigation and water volume monitoring fields. It is applicable to farmland drip irrigation, sprinkler irrigation, greenhouse intelligent watering, orchard irrigation, vegetable field planting irrigation, lawn and garden landscape watering, and urban greening irrigation projects. It can accurately count irrigation water consumption, support automatic water supply control and water-saving management, help agricultural planting realize quantitative irrigation, avoid water resource waste, and provide accurate data support for intelligent agricultural water-saving irrigation and fine planting management.
Installation Method
This water meter supports horizontal and vertical bidirectional installation, adapting to various on-site irrigation pipeline layouts. First, check the water flow direction mark on the sensor body to ensure consistent installation with the pipeline water flow direction. Connect the standard pipe interface with the irrigation pipeline, seal and fix it with thread tape or waterproof connector to prevent water leakage and loose falling off. Then connect the signal wire to the intelligent irrigation controller or data acquisition module, ensuring firm wiring and good waterproof insulation. After installation, open the water valve for pressure test to confirm no water leakage and normal signal output. The whole installation process is simple and efficient, suitable for large-scale on-site construction, pipeline renovation and later equipment replacement in agricultural and garden projects.
