Instrument selection: what a manometer measures best A manometer is used for measuring pressure by balancing a column of fluid. Which range is it best suited for?

Difficulty: Easy

low pressure
moderate pressure
high pressure
atomospheric pressure

Correct Answer: low pressure

Explanation:

Concept/Approach
Manometers (U-tube, differential, micro-manometers) measure pressure or pressure differences via liquid columns and are most suitable for low to modest pressures. High pressures are commonly measured with elastic gauges (e.g., Bourdon tubes). Atmospheric pressure specifically is measured by a barometer.

Final Answer
low pressure
