What is the effect of building a manometer with a tilted tube and scale?

Building a manometer with a tilted tube and scale significantly increases the resolution of measurements. This improvement occurs because tilting the tube allows for a greater length of liquid column for the same pressure differential. Consequently, a slight change in pressure can result in a more noticeable change in the level of fluid along a longer scale, enabling the observer to discern smaller increments in pressure more accurately.

This design enhancement is particularly beneficial when measuring small pressure differences, as it amplifies the visual representation of these differences, thus enhancing overall measurement precision. By increasing resolution, the manometer can provide more detailed and reliable readings, which is critical in many calibration and pressure measurement applications.
