The 2880-OWI Oil Water Interface Transmitter provides reliable monitoring of oil/water interface and emulsions. The 2880-OWI sensing probe continuously monitors the capacitance of the inserted probe. As the interface or emulsion layer (rag layer) crosses over the probe, a proportional 4-20 mA output is provided. Typical applications include oil water separators, oil/water knock-out tanks, treater trains and decanting tanks. The 2880-OWI sensing probe monitors the capacitance field around the probe. A calibration is performed against the oil condition and a water condition. The active portion of the probe is fully submerged into the liquid and sized to your targeted range of interest. As the oil/water interface or emulsion crosses or envelopes the probe, the capacitance change is tracked and an output of 4-20 mA is provided.
