Volume determination system, a vehicle having a volume determination system, and methods of operating such a vehicle

A vehicle, comprising:

• a holding tank comprising a plurality of segments, each segment configured to hold an individual product;
• one or more product sensors for sensing product being added to the holding tank;
• a plurality of suspension assemblies supporting the vehicle;
• a plurality of pressure sensors for measuring a pressure associated with each suspension assembly of the plurality of suspension assemblies;
• and
• a volume determination system comprising:
• at least one processor;
• and
• at least one non-transitory computer-readable storage medium storing instructions thereon that, when executed by the at least one processor, cause the volume determination system to:
• receive an indication from the one or more product sensors when a first segment of the plurality of segments of the holding tank is being filled with a first product via a first filling process;
• responsive to an input that the first filling process of the first segment is complete, receive first pressure measurements from the plurality of pressure sensors;
• based at least partially on the received first pressure measurements, determine a volume of the first product within the first segment of the plurality of segments of the holding tank;
• and
• cause the determined volume of the first product within the first segment of the plurality of segments to be output to an operator of the vehicle.
