VAPOR RETENTION APPARATUS AND METHOD FOR LIQUID VOLUMETRIC TEST MEASURE

摘要

Volatile liquid vapors formed during the pour of the volatile liquid from a volumetric test measure apparatus are contained in a pour vapor-containment apparatus that enhances the rate of vapor formation inside the pour vapor-containment apparatus. The interface between a flow control component on the test measure apparatus and a pour inlet on the pour vapor-containment apparatus creates a positive pressure, vapor-saturated environment so that a sufficient positive vapor pressure is maintained between the interiors of the test measure apparatus and the pour vapor-containment apparatus when the flow control component is inserted in the pour inlet and the test measure apparatus is rotated about vertical during the pour and drain processes so that the vapor-saturated air formed in the pour vapor-containment vessel transfers into the interior of the test measure apparatus during the pour to replace the liquid that is poured out of the test measure apparatus.
