SINGLE COLUMN MANOMETER

 SINGLE COLUMN MANOMETER .

           Single column manometer is a modified form of a U -tube manometer in which a reservoir, having a large cross -sectional area (about 100 times) as compared to the area of the tube is connected to one of the limbs (say left limb) of the manometer as shown in figure. Due to large cross -sectional area of the reservoir, for any variation in pressure, the change in liquid level in the reservoir will be very small which may be neglected and hence the pressure is given by the height of the liquid in the other limb. The other limb may be vertical or inclined. Thus there are two types of single column manometer as :

    1. Vertical Single Column Manometer. 

    2. Inclined Single Column Manometer. 

VERTICAL SINGLE COLUMN MANOMETER

VERTICAL SINGLE COLUMN MANOMETER

  Above figure shows the vertical single column manometer. Let X-X be the datum line in the reservoir and in the right limb of manometer, when it is not connected to the pipe. When the manometer is connected to the pipe, due to high pressure at A, the heavy liquid in the reservoir will be pushed downward and will rise in the right limb.

2.  Inclined Single Column Manometer. 

     

Inclined Single Column Manometer

  

  Figure shows the inclined single column manometer. This manometer is more sensitive. Due to inclination the distance moved by the heavy liquid in the right limb will be more.
