Tips: What materials are used in the turbine water flow sensor, and how does it work?

The domestic turbine water flow sensor is manufactured using high-quality ROHS-compliant materials, primarily featuring a durable aluminum valve body that ensures environmental safety and corrosion resistance. The working principle involves a precision magnetic rotor that spins proportionally to water flow velocity. This rotation is accurately detected by an imported Hall effect sensor, which generates a corresponding digital pulse signal. This signal is transmitted to a controller for real-time flow calculation, enabling precise flow measurement, regulation, and control in applications such as water heaters, industrial equipment, and irrigation systems. The robust construction and reliable pulse output make mini water flow sensor suitable for long-term use in diverse environments.
