l Operating var (variance): This is the difference between Tank Depletion and Pump Sales, In liters
and as a % of tank sales.
l Temp var (variance): This is a temperature difference for the given time period.
l Evap var (Evaporation variance): This is an evaporation difference for the given time period.
l Water var (variance): This is a difference because of a change in the water volume for the given time
period.
l Pump calib (calibration): This is a difference because of the dispenser meter drift (this is only
applicable if a meter offset has been programmed in the Site Mapping).
l Theft: This is a difference that was recorded as a theft (it will be necessary for the Unexpected Sales
threshold to be programmed in the Reconciliation settings in the Tank Setup).
l Unaccounted var (variance): This is calculated as:
n Unaccounted variance = Operating variance – Temp variance – Evap variance – Water
variance - Pump calibration – Theft.
n This is calculated in liters and as a % of sales.
