For accurate measurement of small pressure differences by an ordinary u-tube manometer, it is essential that the ratio ρm/ρw should be close to unity.
This is not possible if the working fluid is a gas, also having a manometric liquid of density very close to that of the working liquid and giving at the same time a well-defined meniscus at the interface is not always possible. So, for this purpose, an inclined tube manometer is used.
For low velocity gas flow, inclined manometers are best suitable for precise measurement of small pressure.

Inclined manometer is used for precise measurement of small pressure in low velocity gas flow.
Explanation:
An inclined manometer is a device used to measure the difference in pressure between two points in a fluid. It consists of a U-shaped tube filled with a liquid, usually a light oil or water, with one end of the tube open to the atmosphere and the other end connected to the fluid whose pressure is to be measured. The difference in height of the two columns of liquid in the tube indicates the pressure difference between the two points.
Inclined manometers are commonly used in fluid mechanics to measure small pressure differences in low velocity gas flows. This is because they offer a high degree of precision and accuracy, and can be used to measure pressures as low as a few mm of water column.
Some of the applications of inclined manometers in civil engineering include:
- Measuring the pressure difference across an orifice plate or a venturi meter in a fluid flow system
- Measuring the pressure difference across a filter or a porous media in a drainage system
- Measuring the pressure difference across a building envelope or a duct system to detect air leaks or pressure imbalances.
Overall, inclined manometers are a versatile and reliable tool for measuring small pressure differences in fluid flow systems, and are widely used in a variety of applications in civil engineering and other fields.
