Airflow measurement is crucial in HVAC systems primarily because it ensures adequate air for comfort and efficiency. Proper airflow is essential for maintaining the desired temperature and air quality within a space. When airflow is measured and adjusted correctly, it helps in:

1. **Comfort**: Sufficient airflow is necessary to evenly distribute heated or cooled air throughout a building, ensuring that occupants experience a consistent and comfortable environment.

2. **Efficiency**: By measuring and optimizing airflow, HVAC systems can operate more efficiently, reducing energy consumption and potentially lowering energy bills. If the airflow is inadequate, the system may work harder to achieve the desired temperatures, leading to increased wear and energy costs.

Inadequate airflow can lead to several issues, such as hot or cold spots in a space, increased humidity levels, and a strain on the system that can affect its longevity. Ensuring adequate airflow contributes directly to the system's performance and the overall comfort of the environment.
