Abstract

Method and apparatus for determining actual liquid volumes in vessels in an incubator rotor that experiences vertical run-out as it rotates past stations that fill the vessels with liquid. Air pressure is used to determine the height of the bottom of each of the empty vessels, and then the height of the liquid that fills the vessels, so that the difference in height is converted into volume to compare with the desired and expected volume for the operation that does the volume-filling.
