The HFM500 Thermal Flow Switch operates on the principle of thermal diffusion, utilizing the temperature difference between two sensors to measure flow rates. As the medium's flow rate increases, the temperature difference decreases, and vice versa. This variation is processed and converted into a standardized electrical signal output, which is then displayed for easy monitoring.
