Inclined Manometer

A manometer with an inclined tube arrangement helps to amplify the pressure reading, especially in low pressure range. A typical arrangement of the same is shown in Fig. L-8.3.

The pressure at O is

                    

The pressure at O is

                    

Equating the pressures, we have

At the same pressure difference, Equations (1) and (2) indicate that inclined tube manometer amplifies the length of measurement by , which is the primary advantage of such type of manometer.
