Hey Chris,

I used to test centrifugal pumps and had to volumetrically measure shaft seal leakage. We'd run a tube from the leakage port into an upended measurement flask/pan arrangement. Remember those school science experiments where you made a barometer? Anyway, as air was displaced by the seal leakage, bubbles (equal to the displaced volume) were collected in the upended flask. I can't remember if there was a data correction for pressure.
