Digital hot wire anemometers and laser Doppler anemometers are new types of anemometers.
1. Digital Hot Wire Anemometer: This instrument uses the change in resistance of the hot wire to detect wind speed and direction. It has the advantages of fast response, high precision and good reliability. field of meteorology, environmental monitoring, etc.
2. Laser Doppler Anemometer: This instrument uses a laser beam to detect the movement of particles in the air to measure wind speed and direction. It has the characteristics of non-contact measurement, high resolution and. high accuracy. , commonly used in wind power generation, aviation, meteorology and other fields.
