In industries, analysis and control of pressure and flow rate control is very difficult, this leads to factory closings and heavy maintenance through PLC and SCADA implementation. Automatic control plays an important role in the continuous operation of the system. In this project, the actual pump performance is tested in terms of pressure, efficiency, and flow rate of the pump for the operating system using a pipeline by crossing pressure in the pipeline with a length of 2 m by connecting pressure sensing equipment. The global control unit SIMATIC S7-1214 as the main decision-making unit that uses this data to make the required decisions. Thus the operation and stopping of the pump as it asks the details related to all other correct information to SCADA to monitor and control the parameters in the pipeline system of the oil pumping station. Then it performs continuous supervision of oil pump station pipeline in order to allow solving any problem and thereby regulating the control system in the structure consists of three layers. These include the first layer of field devices second remote terminal units, and third domain controllers. The signals are sent from the devices via the transmitters to the dedicated PLC boards in the second layer. The central level of SCADA contains a high-speed computer to supervise or operate the station remotely in order to display information through the LABVIEW screens that was showed the final results of pressure and flow rate by operating the system with a voltage rated by Plus With Modulation at a value of 2.73 V for both light and heavy crude oil. It was showed that the pressure value is 0.22bar and the value of the flow rate is 0.25 L/M for heavy oil. While the light is 0.23bar for pressure and the flow rate is 0.652L/M. In addition, to conducting several experiments that show that an increase in the value of the voltage obtained using heavy oil by a value of 3.77 V the pressure value becomes 0.35 bar the flow rate is at 4.78L/M, while light oil has shown the results are that the rated voltage value is 3.77 V, the pressure value is 0.33bar, and the flow rate value through the tube becomes 5.17 L/M. Thus, the greatest value of the voltage 3.77 V, The result when the flow rate through the pipeline increases rapidly, and the pressure decreases, the pipeline passes through the pipeline faster
