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.
Claims2
A sensor device useful for measuring mass displacement in a leaking tank comprising a main body portion having suspension means for attachment to a balance arm or other means for mass displacement detection and a liquid holding portion in said sensor body to hold liquid above the level of liquid in said tank, the cross-sectional area of said liquid holding portion being essentially equal to the cross-sectional area of the body portion in contact with the liquid in the tank, whereby changes in said mass displacement measurement due to evaporative losses are compensated.
