4100-PRO Full Display Profiler
Continuous profiling of oil/water interface and emulsions in tanks
Multiple capacitance probes staggered in an oil/water separator will provide a profile of the emulsion location and thickness.
The 4100-PRO uses multiple sensing probes to measure the capacitance field at distinct points within the tank.
The resulting profile can be used to track the vertical location of an interface/rag layer and the emulsion thickness. The data can be used for flow control, diluent and other chemical injection, and alarms of impending control excursions. This instrument is ideal for trending of process conditions to maximize your oil/water separation efficiency.
