Visualization and control of the liquid levels in storage tanks used for the production of biodiesel at the PavEx Consulting company

PavEx Consulting is a Czech company specializing in road works consulting. In 2004, a system to control the liquid levels in storage tanks used for the production of biodiesel was implemented at the PavEx Consulting company by the Energie MaR company.

The implemented system consists of

• Control and monitoring of three air-conditioning units
• Monitoring of the liquid levels in the storage tanks used for the production of biodiesel
• Control of the entire production process
• Visualization for the main control room's PC

The visualization project was created with the Reliance 3 SCADA/HMI system. The system stores all measured values, alarms, and states. These values can be simply displayed in trends or tables. The measured values of the alarms and states can be displayed in well-arranged reports that are easy to filter.
