Correct Answer - Option 1 : single column inclined manometer
Explanation:
A simple manometer consists of a glass tube having one of its ends connected to a point where pressure is to be measured and another end remains open to the atmosphere.
Common types of simple manometers are:
- Piezometer
- U-tube Manometer
- Single Column Manometer
Differential Manometers measure the difference of pressure between two points in a fluid system and cannot measure the actual pressures at any point in the system. It consists of a U-tube, containing a heavy liquid, whose two ends are connected to the points whose difference of pressure is to be measured.
- Upright U-Tube manometer
- Inverted U-Tube manometer
- Inclined Differential manometer
- Micro manometer
