Process data
Measuring task:
Level and pressure measurement
Measuring point:
Column
Measuring range up to:
6 m
Medium:
Hydrocarbon
Process temperature:
+260 ... +400 °C
Process pressure:
+0.5 ... +4 bar
Special challenges:
Very high temperature, viscous process liquid
Application
The heavy, highly viscous process material and extreme temperature are located in the bottom part of the distillation. For level control of residual feeds, a non-contact measurement is essential for reliability. Monitoring head space pressure at the upper end of refinery columns is important to ensure that the process is operating under ideal conditions.
Your benefit
