Special challenges
High temperature, heavy foam, buildup
Application
Delayed coking units are a critical step in the refining process - this is where downtime, inefficiency, and overfill are not an option. They generate extreme heat during operation and are very large vessels. By monitoring upper vapour phase density, operators can reduce antifoam carry-over and improve continuous productivity with accurate level measurement.
Your benefit
Reliable
Safe measurement even under extreme conditions
Cost effective
Reduced need of foam agents thanks to continuous foam monitoring
User friendly
Easy installation
