In a sealed-tube manometer, the pressure reference is a vacuum, or zero absolute pressure. The most common form of a sealed-tube manometer is the conventional mercury barometer used to measure atmospheric pressure. 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.
