One of the transactions that is often carried out is the fuel oil transaction. This implies the urgency of fuel volume measurement accuracy because it can result in heavy losses to one party when transactions are made. Understanding and research in the field of metering systems is an important aspect in the assets trading (custody transfer), which is the heart of the trade in the fuel oil industry. Therefore, a computing microcontroller-based data acquisition prototype will be made in this final project research for simulation of standard volume dynamic measurement and calculation. Instrument output signal callibration is conducted to further improve simulation performance. The flow mini plant at the ITB MSIK Laboratory will be used to implement and simulate the operating system. The process that will be carried out in this research is field and literature study involving metering skid, study concerning dynamic volume calculation in accordance of API standard, field study and flow mini plant evaluation and data acquisition and dynamic calculation system prototyping and assembly, data sampling test and evaluation of instruments display used, prototyping of standard volume measurement, and analysis of standard dynamic volume calculation data acquisition system. The system consists of instruments data acquisitor with SD Card storage, Human Machine Interface (HMI), OPC server, and spreadsheet for calculation and other requirements. Deviation in volume calculation indication is 0.75% when applied to water, 0.92% on biosolar, 1.36% on premium as well as pertamax, and 1.01% on avtur.
