G2 Gas Fitter Practice Exam

What tool is typically used to measure gas pressure during an installation?

1. Multimeter

2. Gas pressure gauge

3. Pressure cooker

4. Flow meter

The correct answer is: Gas pressure gauge

A gas pressure gauge is the appropriate tool for measuring gas pressure during an installation. This device is specifically designed to measure and indicate the pressure of gases, providing accurate readings that are crucial for ensuring safe and proper installation of gas systems. In an installation context, monitoring gas pressure is essential for verifying that the system is operating within the specified pressure range, which is vital for safety and efficiency. The gas pressure gauge can be connected directly to the gas line and gives a clear reading, helping technicians to make necessary adjustments or identify issues such as leaks. Other tools mentioned, while useful in different contexts, do not serve this specific purpose. A multimeter is primarily used for measuring electrical parameters such as voltage and current, and is not applicable for gas pressure measurement. A pressure cooker is a cooking appliance that utilizes steam pressure for cooking food but bears no relevance to gas pressure measurements in installations. A flow meter measures the rate of flow of a gas or liquid and, while it may provide some insight into system performance, it does not directly measure pressure. Thus, the gas pressure gauge stands out as the correct and necessary instrument for this application.
