What is the purpose of a pressure gauge in a piping system?

• A. To measure temperature of fluids
• B. To measure and display the pressure of fluids
• C. To control the flow rate of liquids
• D. To detect leaks in the system

Answer: (B)

The purpose of a pressure gauge in a piping system is to measure and display the pressure of fluids. This is crucial for several reasons. First, knowing the pressure within a piping system is essential for ensuring that it operates safely and effectively. If the pressure is too high or too low, it can indicate problems such as blockages, leaks, or equipment malfunction.

Pressure gauges provide operators with the information needed to make informed decisions about the system’s performance and to take corrective actions when necessary. Proper pressure levels can help in maintaining system efficiency, preventing damage to equipment, and ensuring the safety of personnel.

Other options are not aligned with the function of a pressure gauge. A pressure gauge does not measure the temperature of fluids; temperature measurement requires a different instrument. It also does not control the flow rate of liquids, as flow control is managed by valves and flow meters. While a pressure gauge can help identify issues that might lead to leaks, it does not serve as a primary leak detection device.
