To measure total pressure in the duct, the manometer is connected as shown on the right of Figure 11. This gauge measures the force of static pressure and velocity pressure which is the total pressure. ... On one side of the manometer static pressure is exerting its force on the fluid column.

What type of pressure does a manometer measure?

A manometer can be designed to directly measure absolute pressure. The manometer in Figure 5 measures the pressure compared to zero absolute pressure in a sealed leg above a mercury column. The most common form of this manometer is the conventional mercury barometer used to measure atmospheric pressure.

What can be used to measure static pressure?

An instrument used to measure pressure is called a “ma- nometer.” The most common manometer is a Magnehelic gauge.
