Q&A: There is a significant discrepancy between the measured oil level in the vertical tank and the value obtained from the subsequent measurement after the previous operation. Please analyze the possible reasons for this discrepancy in the oil level. Answer: Possible reasons include: (1) incorrect reading, (2) wrong position of the measuring rod, (3) temperature changes, (4) leakage or oil migration, (5) foreign objects at the bottom of the tank, (6) malfunction of the oil gauge (such as a twisted hook), (7) movement of the floating roof, (8) incorrect data in previous records.
Answer: Possible reasons include: (1) Incorrect reading, (2) Wrong position of the measuring rod, (3) Temperature changes, (4) Leakage or oil migration, (5) Foreign objects at the bottom of the tank, (6) Faulty dipstick (such as a twisted hook), (7) Movement of the floating roof, (8) Errors in previous record data.
Changes in oil density, sticking of the floating disk
Possible reasons include: (1) reading error, (2) incorrect position of the measuring rod, (3) temperature changes, (4) leakage or oil migration, (5) foreign objects at the bottom of the tank, (6) malfunction of the oil gauge (such as a twisted hook), (7) movement of the floating roof, (8) incorrect data in previous records.
Possible reasons include: 1. Incorrect reading； 2. The measuring rod is in the wrong position ； 3. Temperature changes ； 4. Leakage or oil leakage ； 5. Foreign objects at the bottom of the tank ； 6. The oil dipstick is faulty (e.g., the hook is kinked) ； 7. The floating roof may shift ； 8. The previous ledger data was incorrect.

⑴Reading or recording error, (2) incorrect position of the measuring rod, (3) evaporation of the oil, (4) improper closure of the bottom valve leading to cross-contamination with other tanks, (5) accidental discharge of oil, causing the oil in the tank to be sent out.
