Shore tank corrections

This module helps with common shore tank corrections used during volume measurement. Current calculators include:

• CTSh: shell correction factor (thermal expansion of the tank shell).
• FRC: floating roof correction (displacement effect of a floating roof).

CTSh (Shell correction factor)

CTSh is a multiplicative factor that adjusts a tank volume for shell temperature effects. You provide temperatures and a material coefficient, and the calculator returns CTSh.

How to use

• Enter upper/middle/lower product temperatures (or the values required by your workflow).
• If the tank is not insulated, also provide ambient temperature.
• Enter the tank reference/calibration temperature and the linear coefficient.
• Calculate to get CTSh.

FRC (Floating roof correction)

FRC estimates the volume displaced by a floating roof based on roof weight, density and temperature. It is displayed as an amount to apply per your reporting workflow.

How to use

• Enter floating roof weight.
• Enter density at 15°C in vacuum and the observed temperature.
• Calculate to get FRC.

Notes

• All inputs must be numeric; empty/invalid fields will prevent a meaningful result.
• FRC depends on CTL/VCF behaviour; you should treat it as a calculation aid (not a certification tool).
