when fueling the supplier converts the fuel quantity from litres to Kgs using the density factor which is driven by temperature, not sure who checks the accuracy. i welcome info on practice in ur organisation.
moreover, what % of difference is acceptabel between the computed uplift kgs & actual shown by the guage - say 5%?
from what i remember density goes from .76 to .84 depending on temperature, refinery and fueltype (Russia has some pretty exotic ones) the supplier should give you the dnsity of his fuel and you can compute the uplift with that...... now i dont know what differences in gauged and actual are tolerable, let me inform you though that i know of cases where the difference was 2000 LBS on a 180000lbs uplift. Time and again and again.

Every tech log i've used has a Calculated and Actual for a cross check...and always used .80...
Never had a problem yet, some fuel receipts give us a temp and density, others don't...

that means the fuel density will have a direct impact on the fuel bill as the supplier give fuel in litres but guages read in kgs? if so density accuracy & tolrence is critical...what do u think?
