The pressure gauge is a crucial device used in a boiler system to monitor the internal pressure. It provides real-time readings of the pressure within the boiler, allowing operators to ensure that the system is functioning within safe and appropriate parameters. Monitoring the pressure is essential for maintaining system efficiency, preventing dangerous situations such as pressure build-up, which can result in equipment damage or failure.

A water gauge, while important, is primarily used to indicate water level within the boiler, not the pressure. A thermometer serves to measure temperature, which is also critical in monitoring boiler operation but does not provide information regarding pressure levels. A flow meter is used to measure the flow rate of the fluid in the system, which is important for efficiency and performance but does not directly indicate pressure. Thus, the pressure gauge stands out as the correct answer for its specific role in pressure monitoring within a boiler system.
