A pressure gauge in a boiler system is specifically designed to measure and display the internal pressure of the steam or hot water within the system. This pressure is crucial for the safe and efficient operation of the boiler. Monitoring pressure helps operators understand how well the system is functioning and ensures that it operates within designed safety limits. If the pressure becomes too high, it can indicate a potential safety hazard, prompting the need for immediate intervention to prevent accidents such as explosions or equipment damage.

The other options relate to different aspects of boiler operation but do not pertain to the function of a pressure gauge. For instance, temperature readings are typically provided by temperature gauges, and water level indicators show how much water is present in the boiler. Fuel level monitoring is associated with fuel management systems, not with the pressure gauge itself. Each component in a boiler system has a specific role, and understanding the purpose of a pressure gauge is essential for maintaining safe and efficient boiler operations.
