What is a common tool used in HVAC commissioning for measuring air flow?

An anemometer is a common tool used in HVAC commissioning for measuring air flow because it specifically measures the speed of air moving through a duct or space. This instrument works by rotating in response to the flow of air, allowing for the calculation of air velocity. Once the velocity is known, it can be combined with the cross-sectional area of the duct to determine the volumetric flow rate of air, a critical factor in assessing system performance.

In HVAC systems, accurate measurements of air flow are essential for verifying that the system is balanced and operating as designed. This ensures optimal energy efficiency and comfort levels in conditioned spaces. By allowing technicians to assess air distribution and ensure it meets design specifications, the anemometer plays a crucial role in the commissioning process.
