ABSTRACT:
Electrical contact is made between an electrode and a liquid column to establish current flow between the electrode and the liquid column. The electrode is raised up the liquid column until electrical contact is broken. An additional quantity of liquid is added to the liquid column to cause the column to rise and make electrical contact with the electrode. The electrode is raised up the liquid column until electrical contact is again broken. 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.
