Heavy/ medium crude separation optimization | Endress+Hauser

In medium and heavy crude separation (API 15° to 31° 870 to 960 kg/m 3 (7.3 to 8 lb/gal)), it can be challenging to measure the overall level as well as the interface accurately with a single device. In these applications a rag layer (emulsion) often exists. If this rag layer exceeds 5 cm (2 inches), a standard guided wave radar device will not be able to measure the interface.
