When measuring airflow velocity, what tool is primarily used?

The primary tool used for measuring airflow velocity is the anemometer. This instrument is specifically designed to measure the speed and direction of airflow in various environments, such as ducts, ventilation systems, or open air. Anemometers can come in different types, including mechanical, electronic, and hot-wire variations, each offering precise readings of velocity.

Using an anemometer allows millwrights and technicians to assess and optimize airflow in systems effectively, which is crucial for maintaining proper functioning of HVAC systems, improving efficiency, and ensuring comfort in indoor settings. Understanding airflow velocity is also vital for analyzing system performance, detecting issues, and ensuring compliance with engineering specifications.
