Process data
Measuring task
Level measurement and point level detection
Measuring point
Tank
Measuring range up to
10 m
Medium
Various hydrocarbons
Process temperature
+65 … +345 °C
Process pressure
+1 … +20 bar
Special challenges
High pressure, high temperature, changing products, very fast filling process
Application
The blowdown drum is designed to allow the refinery to release any process or byproduct liquids including hydrocarbons, in a safe and controlled way that protects plant equipment and personnel. The blowdown drum can see rapid filling at high pressures and temperatures. Because of the mixture of products, density and viscosity can also fluctuate, so the level must be measured quickly and reliably.
Your benefit
Reliable
Unaffected by density fluctuations, fast level, temperature and pressure changes
Cost effective
Maintenance-free operation
User friendly
Simple adjustment and installation
