Discussion on gas temperature and pressure compensation
Thread Content
Why are the temperature and pressure for gases, as well as the reference temperature and pressure, set at the design values rather than the actual temperature and pressure during operation? Using the operating temperature and pressure as a reference isn’t it more accurate?
You’re right; if the design temperature and pressure are very close to the actual operating temperature and pressure, no compensation is needed.
Since the flow meter calculations are based on the design temperature and pressure, compensation is necessary because there are differences between the actual operating temperature and pressure and the design values; compensation addresses these differences.
Pressure and temperature compensation for gases involves converting the pressure and temperature values under actual operating conditions into gas flow rates under standard conditions, namely 1 atmosphere and 20°C. The design pressure and design temperature represent the maximum pressures and temperatures encountered in the pipeline, and they are used to determine the appropriate pressure resistance required for the pipes.
