CERTIFICATE OF CALIBRATION - N0. PS060000This table gives volumes in litres for millimetres of product measured over the dip plate. The tank is a vertical "in/out" lapped tank with a fixed roof, an internal blanket and a coned up floor. The first red highlighted area on page 4 of the table is below the high point of the floor. In this zone the average values from the bottom of the page should not be used. Intermediate volumes in thezone should be interpolated from the nearest values in the table. Accurate volumes cannot be obtained from the tables within the zone of partial displacement of the blanket, which is also highlighted in red on the table. Refer to the Floating Blanket Correction Table (page 3) for the zone levels and treatment of the blanket in the calculation of tank volumes.
