Accurate crude oil measurement at the metering station is one of main aims in oil terminal. The main objective is
to decrease or remove any error at the metering station. It is found that crude oil temperature at metering station has
big effects on measured volume and may cause big uncertainty at the metering point. The main flow as travel
through the pipe line pick up the solar radiation and heat up. This causes the crude oil temperature at the metering
point to rise and higher uncertainty to be created. The amount of temperature rise is depended on main pipeline flow
rate. In Kharg Island, there is about 3 km distance between crude oil storage tanks and metering point. The crude oil
flows through the pipe line due to gravity effects as storage tanks are located 60m higher in height comparing to the
metering point. The amount of the flow rate could be controlled by the appropriate valves. In this study, based on
climate and geographical conditions of the Kharg Island, the temperature at the metering point has been calculated
and the effect of main pipe line flow rate has been investigated. Further, the uncertainty in measured system due to
temperature rise has been studied.
