What is a key feature of the inclined "U" tube manometer?

The inclined "U" tube manometer is recognized for its increased accuracy in pressure measurement compared to the standard vertical "U" tube manometer. The design of an inclined manometer allows for a longer liquid column read along a sloped scale, which provides finer resolution and makes it easier to detect small changes in pressure. Because the liquid travels a longer distance along the scale for a given change in pressure, the readings can be taken more precisely.

In terms of applications, inclined manometers are often utilized in scenarios where precise pressure measurements are critical, such as in labs or when monitoring very low pressures. This heightened accuracy makes the inclined "U" tube manometer a preferred choice over its vertical counterpart for applications requiring precise calibration and measurement.
