Abstract
A system with container volume tracking includes a pump receiving a line connected to a tracked container, an air sensor to detect air in the line, and a controller coupled to pump and sensor. The controller is configured to monitor pump operation, and determine a volume removed from the container based thereon. If the volume removed is less than a first percentage of a target volume and there is air, continue operation after an air purge. If the volume removed is more than the first percentage and less than a second percentage and if there is air, prompt the user for an input, and continue operation after an air purge if a first input is received or end operation if a second input is received. If the volume removed is more than the second percentage and if there is air, end operation.
