Problem: build a combined anemometer and wind vane where the pivots for both sensors are coaxial. Solution: turn an old universal motor into a step-wise potentiometer for the wind vane, and then ...

To measure wind speed and direction, most people turn the traditional cup anemometer and wind vane. Another less-known method is to use an array of ultrasonic transducers, which doesn’t need … ...

Thermal anemometers are generally the first choice for accuracy, but are inappropriate for determining airflow direction. A smoke source can be used in conjunction with the thermo-anemometer to ...

Cup anemometer with separate wind vane - Uses three cups to measure wind speed, while a wind vane measures wind direction. The vane always points in the direction that the wind is coming from and ...

A thermo-anemometer with a telescopic articulated probe, deflecting vane anemometer with a low-flow probe, or a rotating vane anemometer can be used for this type of measurement. • A thermo-anemometer ...

The HHF144 handheld, rotating vane hygro-thermometer anemometer promises highly accurate humidity, air velocity, and temperature measurements in harsh environments via a user- ...
