The Control of the Metering Valve for the Petroleum Depot Based on the Trapezoidal Flow Rate Algorithm

Automating the control of petrol depots for tank trucks is a requirement today. The automation system will reduce manual operations, improve productivity and avoid operator errors. In this paper, an algorithm to control the metering valve for petroleum depots outputting tank trucks based on the trapezoidal flow rate algorithm is introduced. To implement the control algorithm, the paper also proposes a solution to automatically control the pump, control the valve, receive feedback on temperature and the actual number of liters output. This control algorithm has been tested and applied in practice at the western petroleum depot at Tra Noc Industrial Park, Can Tho city, Vietnam. This algorithm has worked well and helped the petrol depot for tank trucks to be more flexible, convenient, and accurate.
