Which device is used to measure boiler system pressure?

• A. A flow meter
• B. A temperature sensor
• C. A pressure gauge
• D. A humidity gauge

Answer: (C)

A pressure gauge is specifically designed to measure the pressure within a boiler system. It provides critical information about the operating conditions, allowing operators to ensure that the system is functioning within safe and efficient ranges. Pressure is a vital parameter in boiler operations, impacting not only efficiency but also safety.

The pressure gauge typically displays pressure readings in psi (pounds per square inch) or bar, and assists in monitoring for any abnormalities that could indicate issues such as leaks or mechanical failures. This capability is essential because maintaining appropriate pressure levels is crucial for optimal boiler performance and safety.

In contrast, devices like flow meters measure the flow rate of liquids or gases, temperature sensors monitor thermal conditions, and humidity gauges assess moisture levels in the air. While these devices are important to overall system monitoring, they do not provide the pressure measurements necessary for boiler operation management.
