Which items are included in cargo measurement equipment?

• A. Gauging bob
• B. Indicating paste
• C. Thermometer
• D. All of the above

Answer: (D)

Measuring cargo quantity and condition relies on tools that determine liquid depth, mark the reading, and monitor temperature. The gauging bob is a weighted probe used in tank gauging to determine how deep the liquid is, giving the ullage or liquid depth. The indicating paste is applied to the gauging rod so the liquid surface level can be read clearly when the rod is withdrawn, which is especially helpful in reduced visibility or when residue is present. The thermometer records the cargo temperature, which affects density and total volume and is needed for temperature-corrected quantity calculations and for assessing the cargo’s state. Since all three types of devices play essential roles in accurate cargo measurement, the best choice is all of the above.
