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

The function of a pressure gauge in a piping system is to monitor internal pressure. This device provides real-time readings of the pressure within a system, which is essential for ensuring that operations remain within safe and efficient limits. Monitoring pressure helps prevent potential system failures or hazards that could occur due to excessive pressure. It allows operators to make informed decisions regarding system adjustments and maintenance.

While measuring fluid velocity, checking material thickness, and detecting temperature changes are important aspects of managing a piping system, they are not the primary functions of a pressure gauge. A pressure gauge specifically focuses on providing information about the pressure conditions within the system, making it a crucial tool in maintaining operational safety and efficiency.
