The document discusses the hidden costs of temperature measurement errors when measuring cargo quantities during transfers. It notes that an error of just 1.6属C/3属F can lead to a difference of 180 barrels in a 150,000 barrel tank, potentially impacting the value of a gasoline cargo by around $19,440. However, 90% of portable electronic thermometers used for these measurements are not properly verified per industry standards, meaning the reported temperatures may have undetected biases. The document concludes that specialists should be consulted to properly determine cargo tank temperatures and avoid these measurement errors.
