Automated Fuel Pumping System

Posted in Energy and Utilities, HMI and SCADA, Manufacturing Automation and Intelligence, Oil and Gas Engineering, PLC Programming


DMC programmed a fuel management system that feeds generators to provide emergency back-up power to a mission critical 24-7 building. The end result was an automated fuel pumping system to keep the generators running as long as needed. 


The client's building relied on several large back-up generators to provide power to the building in the event of an emergency until power from the grid is restored. DMC programmed the fuel pumping system that feeds each generator, automating the monitoring and transfer of diesel fuel in long-term storage tanks to smaller tanks for immediate use. 

The solution utilized several hardware-redundant Automation Direct DL305 PLCs for a distributed control system. System status and local control was available through local HMIs present throughout the distributed control system.
