Process data
    Measuring task:
    
    Level and pressure measurement
        Measuring point:
    
    Tank
        Measuring range up to:
    
    0.4 m 
        Medium:
    
    Hydrocarbons
        Process temperature:
    
    -50 … +400 °C
        Process pressure:
    
    -0.5 … +2 bar
        Special challenges:
    
    Buildup, contamination and high temperatures
Application
The process temperatures in a distillation column place high demands on the measurement technologies deployed. The boiling point of the distillate frequently exceeds 400 °C. The aim is to achieve the highest possible product throughput for cost-effective operation of the plant. This means the raw material replenishments need to be optimally controlled by level and process pressure measurement in the column.
