Question

In order to increase sensitivity of u-tube manometer, one leg is usually inclined by an angle . what is the sensitivity of inclined tube compared to sensitivity of u-tube?

Answer 1

The sensitivity of the well manometer can be adjusted by changing the angle α and can be some 30 times that of the U-tube. This type is also often called a micromanometer due to its ability to measure very small pressure differences. Several other types of micromanometers and fluid manometers are also available.
