A balometer measures what?

• A. Magnehelic gauge
• B. Breathing Zone
• C. Smoke Tubes
• D. Balometer

Answer: (D)

Measuring airflow from a diffuser or grille requires a capture hood that encases the opening and directly measures the volume of air passing through per unit time. This device, often called a balometer, provides a direct reading of airflow, typically in CFM or L/s, which is essential for balancing a ventilation system and verifying that each diffuser delivers the designed amount of air. The other options aren’t measurement tools for airflow. A Magnehelic gauge is a differential pressure gauge, useful for assessing pressure differences but not the actual flow rate. Smoke tubes visualize airflow patterns and directions, helping you see where air moves, but they don’t quantify how much air is flowing. The term “breathing zone” refers to the region around a person where they actually inhale air, a concept about exposure and ventilation effectiveness rather than a device that measures flow. So, a balometer is the tool designed to measure the actual airflow from a diffuser, making it the correct choice for this question.
