A level measurement system configured to measure minute changes in fluid level. The system integrates a linear variable differential transformer (LVDT) to provide highly accurate level measurement. Low friction materials and a timed vibrator are used to minimize fluid static friction effects on level measurement. A second LVDT can be utilized to compare the level of a fluid containment structure with level changes caused by environmental factors such as evaporation, tidal effects, wind, or the like. The system also includes a computing device to record and compare level changes over time. A housing connects the elements of the system.
