What does an inclined manometer measure?

An inclined manometer is specifically designed to measure low levels of pressure, making it particularly useful for applications such as assessing air pressure within HVAC duct systems. It utilizes a column of fluid, often water or mercury, to provide precise readings of pressure differences. The incline of the manometer enhances sensitivity, allowing it to detect small pressure variations that may occur in air conditioning and heating systems. This capability is essential for ensuring that the system operates efficiently and effectively by monitoring and balancing air pressure as needed. Thus, an inclined manometer is a vital tool for HVAC professionals, aiding in diagnosing and maintaining proper airflow in ductwork.
