Something along these lines:

Basically, face a webcam at the sight glass then use OpenCV to determine where the edge is between liquid and air, then calculate the volume based off of the calibrated pixel location of the interface.
Seems like a fairly straight forward, no touch way to calculate volume with a fairly low cost if you are already using some sort of computer to automate things.
