What does 'Total Observed Volume (TOV)' exclude from its measurement?

The correct understanding of what 'Total Observed Volume (TOV)' refers to is crucial in the context of measuring liquid volumes. TOV specifically refers to the total volume of liquid observed at a specific temperature, which typically does not include any free water that may be present in the sample. This is important because free water can change based on temperature and condition, potentially leading to inaccuracies in volume readings if included.

The exclusion of free water helps ensure that the measurement reflects only the liquid portion that the TOV aims to quantify, providing a clearer picture of the actual liquid content being measured. In contrast, sediment, any oil in the sample, and gas components would typically be considered in a broader assessment of the entire liquid sample rather than in the specific measurement of TOV. This exclusion is key for accurate reporting and compliance in various operations involving tankerman activities and liquid measurements.
