ABSTRACT:
An electrode is lowered toward the surface of a liquid column until electrical contact is made between the electrode and a liquid column to establish current flow between the electrode and the liquid column. The electrode is raised from the liquid column. An additional quantity of liquid is added to the liquid column to cause the column to rise. The electrode is lowered toward the surface of the liquid column until electrical contact is again effected. The distance of travel of the electrode is measured as a determination of the rise in height of the liquid column and of the additional volume of liquid added to the column.
