WebPressures under water differ from those under air only because the weight of the water must be added to the pressure of the air. Atmospheric pressure can be measured by any of several methods. The common laboratory method uses a mercury column barometer. The height of the mercury column serves as an indicator of atmospheric pressure. WebDisplacers work on the Archmedes’ principle. As shown in Figure 2, a column of solid material (the displacer) is suspended in the vessel. The displacer’s density is always greater than that of the process fluid (it will sink in the process fluid) and it must extend from the lowest level required to at least the highest level to be measured.
