Application
It is important that a desalter unit runs efficiently to prevent corrosion to downstream equipment. When the crude oil mixes with the emulsifying chemicals and water, the resulting emulsion layer makes it difficult for standard level measurement technologies to reliably track the interface. Radiation-based measuring instruments are not affected by this and allow to track the interface even with thick emulsion layers present in the tank to make sure that the desalting process can be controlled efficiently at maximum throughput.
Your benefit
Reliable
High measuring precision, independent of process conditions
Cost effective
External mounting to the vessel, easily retrofitted
User friendly
Simple air and water calibration for fast commissioning time
