What type of pressure is typically measured in a boiler system?

In a boiler system, the most commonly measured type of pressure is gauge pressure. This is because gauge pressure measures the pressure relative to atmospheric pressure, which is relevant for most operational considerations in a boiler. Gauge pressure indicates how much pressure is present in the system above the surrounding atmospheric pressure.

Measuring gauge pressure is crucial for safety and efficiency, as boilers operate under specific pressure conditions that need to be closely monitored. If the gauge pressure rises too high, it can indicate potential hazardous conditions, which could lead to equipment failure or even accidents.

Relative to the other types of pressure mentioned, absolute pressure includes atmospheric pressure in its measurement, which is not typically necessary for boiler operations. Vacuum pressure refers to pressure below atmospheric pressure and is more relevant in specific contexts, while static pressure usually relates to fluids at rest rather than the dynamic and operational pressures experienced in a boiler system.
