Which type of scale does a well-type manometer utilize?

A well-type manometer utilizes an inclined scale, which is designed to enhance the accuracy of pressure measurements by maximizing the distance that the liquid column moves for a given change in pressure. The inclination of the scale allows for more precise readings because the same pressure difference results in a greater height difference on the incline compared to a vertical scale.

This design is particularly advantageous in situations where very small pressure differences need to be measured. By using an inclined scale, the user can achieve finer resolution and therefore more accurate readings. Since the liquid's movement is amplified along the incline, it translates small pressure changes into larger vertical displacements, making it easier to read and interpret the results.

An inclined scale’s design is beneficial in various applications, such as laboratory settings, where precise measurements are crucial for experiments and evaluations.
