The accuracy in the process of oil custody transfer is the main thing for reaching agreement to both transacting parties. Oil custody transfer should meets the standard of industry, metrology, local government’s regulation and taxation, as well as sales agreement. In this research, batch controller system was designed to accurately regulate and control volume of oil custody transfer using metering system. Batch controller’s system was simulated with simulator. The simulator was designed by modeling metering skid’s system in meter run’s mini plant of MSIK Laboratory into Simulink software. Several steps of simulator design process were established: acquisition of data instrument of metering skid from meter run of mini plant in MSIK Laboratory, system modeling based on data acquisition’s result, design of Simulink block diagram, and integration with automated device by system architecture. Also, in this research, there was flow rate control when pump being activated. This research used proportional-integral controller (PI). The results obtained by the PI controller is the accuracy of the output volume gets an increase, 4.481% on a 2 liters transaction volume. The PI controller also made the flow rate response reach the setpoint and the batch duration was 54 seconds faster from 1 hour 58 minutes 47 seconds at a transaction volume of 4000 liters. This study also proves that the effect of temperature is greater than the pressure with a standard deviation of 2.623 liters. Fluid density also affected the standard volume deviation with the flow meter reading, in the water of 6.35 liters in Biosilar of 7.926 liters, in Premium, Pertalite, and Pertamax of 11,346 liters for a transaction volume of 1000 liters.
