Tilt correction

ℹ For horizontal tanks on a slope, the observed dip differs from the true level. Enter dip readings at both ends or a known tilt angle to calculate the correction.

Temperature & density compensation

ℹ VCF = 1 / (1 + α × ΔT). Corrects observed volume to standard conditions at 15°C.

Shell length calculator

Derive shell length when you don't have it, or verify an existing value.

ℹ Use when you know the total nominal capacity from the nameplate and the tank diameter.
