Fill volume of a liquid in a sealed, transparent container is determined by rotating the container about a transverse axis so as to confine the air to a generally cylindrical air pocket about the transverse axis of rotation. Machine vision methods and apparatus are used to capture an image of the container, including the air pocket, for measuring the size of the air pocket. A common volume of the container is defined as a generally cylindrical region intermediate upright and inverted liquid levels. The common volume and the air pocket volume are used to determine the liquid fill volume so that all measurements are acquired in a central portion of the container having a regular geometric shape.

A non-destructive method of determining a fill volume of a first fluid in a sealed container that also contains a second fluid having a lower density than the first fluid, the container having a substantially symmetrical central region, comprising the steps of: determining a common volume within the central region of the container intermediate an upright fluid level and an inverted fluid level, such that the first fluid fill volume equals a sum of the second fluid volume plus the common volume; determining the second fluid volume; and summing the second fluid volume and the common volume to determine the first fluid fill volume.
