What device is used to measure gas delivery pressure from the meter?

• A. Manometer
• B. Pressure gauge
• C. Barometer
• D. Flow meter

Answer: (B)

The device used to measure gas delivery pressure from the meter is a pressure gauge. This instrument is specifically designed for accurately measuring the pressure of gases and liquids in various systems, including gas lines. Pressure gauges are essential for ensuring that gas appliances operate within their required pressure ranges, helping to maintain safety and efficiency in gas delivery systems.

Manometers are typically used for measuring low pressure differences, but for general gas delivery pressure measurement, pressure gauges are more commonly utilized due to their ease of use and range of pressure readings. While barometers are utilized for atmospheric pressure measurements and flow meters are used to measure the flow rate of gases or liquids, they do not serve the primary purpose of measuring gas delivery pressure from the meter. Thus, pressure gauges are the appropriate choice for this application.
