Introducing the FH-501 Hall Flowmeter Funnel, a robust solution engineered for precise flow rate detection in liquid dispensing systems. This sensor utilizes advanced Hall effect technology to convert the flow of liquid into electrical pulses. Available in multiple aperture sizes (1.0mm to 2.5mm), it offers accuracy levels of ±2%, ±3%, and ±5%. The device features a durable plastic housing with a funnel-shaped inlet and outlet, ensuring smooth fluid dynamics and minimal pressure loss. Designed for easy integration, it operates stably within a wide voltage range and is built to last with a rated life of 50,000 hours.
Product Features
High Measurement Accuracy & Stable Performance
Equipped with high-sensitivity Hall induction chips, the flowmeter delivers precise flow detection with low zero drift and excellent repeatability. It maintains stable measuring accuracy under different water pressure and temperature conditions, effectively avoiding measurement errors caused by fluid fluctuation, ensuring long-term consistent and reliable data output for household appliance fluid systems.
Integrated Funnel Integrated Design
The optimized integrated funnel structure integrates flow detection and fluid diversion functions, replacing complex split installation structures. The streamlined inner wall design reduces fluid resistance and avoids liquid residue, ensuring smooth fluid circulation while improving overall detection efficiency, which is more in line with the compact structural design requirements of household appliances.
Durable & Food-Grade Safe Material
The product adopts high-quality corrosion-resistant, high-temperature resistant engineering plastic and food-grade stainless steel optional materials, which are non-toxic, odorless and wear-resistant. It can adapt to long-term water flow impact and frequent start-stop working conditions, effectively resisting scale and corrosion, with a service life far exceeding traditional flow detection parts, meeting household appliance safety standards.
Strong Compatibility & Anti-Interference Ability
With built-in anti-electromagnetic interference and anti-water surge design, it can operate stably in complex household electrical environments without being affected by surrounding circuit signals. It is compatible with most mainstream household appliance control boards and intelligent systems, featuring wide voltage adaptation and strong environmental adaptability.
Working Principle
Turbine Rotation: As liquid flows through the funnel, it drives an internal turbine or impeller.
Magnetic Field Change: The rotating impeller has embedded magnets. As they spin, they create a changing magnetic field.
Signal Generation: A Hall sensor detects these magnetic field variations and generates corresponding electrical pulses.
Flow Calculation: The flow rate is directly proportional to the pulse frequency, allowing the host system to calculate the exact volume of liquid dispensed.
