During LPG testing, when should temperature readings be taken at the prover?

Taking temperature readings at the end of the test is critical because it allows for the accurate determination of the volume of liquid measured during the LPG testing. The density of liquid petroleum gas (LPG) can be significantly affected by temperature changes; as temperature increases, the volume of the gas can expand. Therefore, measuring the temperature at the conclusion of the test ensures that any volume calculations are based on the final temperature, which is necessary for assessing density and converting volume to a standard condition.

This approach also helps maintain consistency in measurement verification processes. By capturing the temperature at the end, you ensure that any adjustments or calculations performed afterward accurately reflect the conditions under which the LPG was measured, leading to more reliable and reproducible results. Accurate temperature data is essential for compliance with industry standards and for the integrity of the testing procedure.
