What do you use to measure airflow in HVAC systems?

An anemometer is the instrument specifically designed to measure airflow in HVAC systems. It works by detecting the speed of air movement, usually in cubic feet per minute (CFM) or other similar units. Understanding airflow is crucial in HVAC applications, as proper air movement directly impacts comfort levels, efficiency, and overall system performance. Anemometers can be used in various ways, such as handheld devices or larger stationary monitors, to provide accurate readings of air velocity, which can then be used to calculate airflow rates.

Other instruments mentioned, such as thermometers, measure temperature, while manometers are used for measuring pressure differences, and psychrometers assess humidity and wet-bulb/dry-bulb temperatures. While each of these tools has its role in HVAC diagnostics and performance analysis, anemometers are uniquely suited for measuring airflow, making them the correct choice for this particular application.
