What is typically used to measure steam pressure in a boiler system?

In a boiler system, a pressure gauge is the essential instrument used to measure steam pressure. This device is designed specifically to display the pressure of the steam within the boiler, which is crucial for monitoring the system's operation.

Maintaining the correct steam pressure is vital for ensuring safety and efficiency. If the pressure is too low, the boiler may not function effectively, leading to inadequate heat or energy production. Conversely, if the pressure is too high, it can create hazardous situations, potentially damaging the boiler or posing safety risks.

Other instruments, such as a thermometer, flow meter, or level indicator, serve different purposes within a boiler system. A thermometer measures temperature, a flow meter tracks the flow rate of steam or water, and a level indicator monitors the water level in the boiler. While these tools are important for overall system management, only the pressure gauge directly measures steam pressure, making it the correct choice in this context.
