What type of instrument is likely to use a manometer for measurement?

A manometer is specifically designed to measure pressure differences between two points or the pressure of a fluid against a known reference. Typically, it consists of a U-shaped tube filled with liquid (often mercury or water) and is used to determine the pressure exerted by gases or liquids.

For instance, when measuring pressure, one side of the manometer is exposed to the pressure being measured, while the other is open to the atmosphere or another reference pressure. The difference in liquid levels between the two sides indicates the pressure difference, making it a crucial tool in various applications, such as HVAC systems, hydraulic systems, and gas pressure measurements.

Other measurements, such as flow rate, temperature, and volume, rely on different types of instruments designed specifically for those purposes, rather than a manometer. Flow rate instruments might include rotameters or flow meters; temperature is measured using thermometers or thermocouples; and volume would typically involve graduated cylinders or flow measurement devices.
