I. Working Principle
The HNF20-B operates based on the proven turbine measurement principle: as fluid flows through the sensor chamber, it drives the rotation of a high-precision turbine impeller. The impeller's rotational speed maintains a stable, linear relationship with the fluid flow velocity.
A non-contact detection module captures the impeller speed in real-time and converts it into standard pulse or analog signals to calculate the flow rate. This structural design ensures rapid response and excellent repeatability, specifically engineered for clean, low-viscosity liquid media.
