What is the function of a pressure gauge in a piping system?

The function of a pressure gauge in a piping system is to indicate pressure. A pressure gauge provides critical information about the internal pressure within pipes and other components of the system. By measuring the pressure, it allows operators to monitor the performance of the piping system, ensuring that it operates within safe and specified pressure ranges. This information is vital for diagnosing potential problems, maintaining efficiency, and ensuring safety, as excessive pressure can lead to system failures or leaks.

In contrast, regulating flow, measuring temperature, and controlling fluid levels are functionalities managed by other specific devices and systems. For instance, flow regulators are specifically designed to manage the rate of fluid movement, temperature gauges focus on heat levels rather than pressure, and level controllers are used to maintain or monitor the fluid's height in tanks or vessels. Each component has a distinct role that contributes to the overall functioning of fluid systems.
