When is an inclined manometer commonly used?

An inclined manometer is specifically designed to measure very small pressure differentials with high accuracy. The inclination of the tube allows for a greater length of fluid column to represent the pressure difference, making it easier to read small changes in pressure. As the angle of the manometer increases, small changes in height translate to larger readings, which improves the resolution and sensitivity of the measurement.

The design of an inclined manometer is particularly advantageous in applications where precise pressure readings are necessary, often found in laboratory settings or where slight variations in pressure are critical for system performance or safety. Since options highlighting high-pressure measurements or situations where accuracy is not vital are not aligned with the functionalities of an inclined manometer, the focus on measuring very small pressure differentials reinforces the context where it is most applicable.
