Abstract

A sensor for measuring leakage from a liquid containing tank comprises a main body portion suspended from a balance arm or other mass displacement detector and has a liquid holding portion in the main body. The cross-sectional area of the liquid holding portion is essentially equal to the cross-sectional area of the main body portion in contact with the liquid in the tank. This arrangement enables evaporation losses to be compensated.
