Manometer Diagram. The differential manometer is a device used to measure the pressure difference between two points in a pipe or in two different pipes. Coloured fluid is poured into the reservoir of each manometer and allowed to flow into the capillary tube.
It can be seen that the level of the filling liquid in the leg where the pressure is applied ie. The manometer consists of a metal well of large cross sectional area connected to a glass tube or limb. A manometer is a device that we use to measure the pressure of the pipelines cab be of gas water liquid etc also it is usually referred to as a u shaped tube that is filled with a liquid.
Two rubber bungs are now taken fitted with tubes as shown in the diagram.
In this case the tank contains gas and we would like to determine the pressure in the tank based on the manometer reading h. In the majority of cases this will relate to a gauge which consists of a u shaped glass tube which is filled with mercury or some other liquid. Find the relation between gases x y z in the manometers given below. Close the spring clips.
