What “Aerometric Filler” means here

Parker's 1948 squeeze filler for the 51: a pli-glass sac inside a metal sleeve with a breather tube, pressed a few times to fill. The sacs rarely fail, which is why aerometric 51s are the daily drivers he recommends; when they do, it is a clean and a resac. On his repair list ("Aerometrics").
