All factors would cause inaccurate data collection during an overfill test on manifolded tanks, EXCEPT?

• A. Associated Vapor Pockets
• B. Difference In Temperature
• C. Difference In Diameters Of Tanks
• D. Different Tank Types

Answer: (D)

The main idea is understanding what factors can distort readings in a manifolded overfill test. Vapor pockets inside tanks can hide or shift the actual liquid volume, leading to readings that don’t reflect true fill amounts. Temperature differences change the liquid’s density and volume, so the same mass of liquid can show different heights in different tanks. Differences in tank diameters alter the relationship between volume and height (the same volume will produce different liquid heights depending on cross-sectional area), which can skew how the manifold records the overall fill behavior. Different tank types, by contrast, do not inherently introduce a single, consistent source of measurement error in the data collection path for a manifolded system; the test can still monitor the combined response of all tanks. So the factor that does not automatically cause inaccurate data collection is having different tank types.
