What does the boiler steam pressure gauge measure?

Temperature in degrees Celsius
Pressure in psi
Water level in inches
Flow rate in gallons

The correct answer is: Pressure in psi

The boiler steam pressure gauge specifically measures the pressure of the steam within the boiler system, typically expressed in pounds per square inch (psi). This is crucial for monitoring the performance and safety of the boiler, as it indicates whether the system is operating within its designed pressure limits. Understanding the steam pressure is essential for ensuring proper operation, for preventing overpressure situations that could lead to equipment failure or safety hazards, and for maintaining efficiency within the system. The other choices relate to different measurements that do not pertain to the steam pressure gauge: temperature readings in degrees Celsius monitor heat rather than pressure, water level measurements in inches indicate the amount of water in the boiler, and flow rate in gallons measures the volume of liquid moving through a system, which is unrelated to the pressure of steam in the boiler.
