Bottom loading arm has been widely applied in petrochemical plants and oil refineries and depots to loading light oil (i. e. Gasoline, diesel, jet fuel, and naphtha) and benzene (benzoyl, methylbenzene, dimethyl benzene). Our company designed an automatic Quantitative Loading Control System which is fully functional, technical advanced, structure reliable, and handle easier and work stable. This system can complete parameter setup, data collection, flow temperature compensation, quantitative control, procedure operation, overfill prevention and antistatic interlock, operation monitor, and report printing etc, in loading process. It also offers communication interface to connect external PCS. The quantitative oil loading control system is very helpful for the bottom loading arm to give its maximum performance by increasing the precision, speed, reducing human error and pollution, thus improving the efficiency and saving energy. Our objectives are safety, labor efficiency, ease-of-use, time saving, and ultimately higher returns. 

Function
The system has distributed field control and centralized remote control function. In order to ensure reliability, these two control functions can be simultaneously available. When it occurs abnormal cases in the control room, the operators can continue loading works at individual loading lots by field controller. 

Field controlled loading: Operators could conduct loading on-site loading lots based on the Operator's Manual. 
Remote controlled loading: All loading lots would be accessed through the central control room where operators could conduct loading to single or multiple tankers. The oil loading system data is consistent field showing data, and generates complete loading information. 

Characteristic
Distributed control and centralized management
Flexible architecture that supports big expansions
Combination field condition and user's need with Strong application and effectiveness
Adjusted organize data display format
Automatic monitor and control valve on site
High reliability by rapid switching between master/slave set

Applications
Petrochemical plants, large oil depots, light oil, benzene, industrial chemicals, tank truck loading.
