What kind of equipment is primarily reliant on installing nozzles on pressure vessels?

The correct choice pertains to flow measurement equipment. Flow measurement devices, such as flow meters, often utilize nozzles as critical components for controlling and measuring the flow of fluids. The design of a nozzle typically facilitates the precise measurement of flow rates by creating a differential pressure that correlates with the flow velocity, enabling effective monitoring and assessment of fluid dynamics within a system. This reliance on nozzles is particularly significant in applications where accurate flow measurement is essential for operational efficiency and safety.

Although other types of equipment may also incorporate nozzles, they are not primarily dependent on them for their primary function. Heating equipment, cooling equipment, and pressure regulation equipment tend to focus more on heat transfer and pressure management, respectively, rather than on the direct measurement of flow rates, which is where flow measurement equipment stands out in its necessity for nozzle installation.
