The core principle of an anemometer is based on heat exchange: a heated metal wire (hot wire) dissipates heat in the fluid, and the temperature drop is directly proportional to the wind speed. By measuring the change in resistance, the flow rate can be calculated. The probes are divided into thermosensitive type (0-5m/s), impeller type (5-40m/s), and pitot tube type (40-100m/s), respectively suitable for low-speed, medium-speed, and high-speed scenarios. The probe materials need to be heat-resistant. The thermosensitive type is applicable from -70℃ to +350℃, special impeller probes can withstand up to 350℃, and the pitot tube is more suitable for extreme high-temperature environments.
