Dear Sir, Please help on following DTI usage. I am using EXCEL sheet as attached for showing volume of tank. We have 2 conditions. 1. NEGATIVE TRIM 2. POSITIVE TRIM. trim is calculated by our sensor. The height of the liquid is also calculated by pressure sensor.  From the liquid height according to positive or negative trim, select the volume from the cell. This value want show in a numeric box. For example, I know my tank list is positive and sounding is 0.25 a
