The iPhase™ Level Measurement and Water Profiler
High-quality and accurate inductive profiler
The iPhase™ profiler measures the oil water interface, provides accurate measurements of water conductivity and thereby the oil in water profile inside hydrocarbon separators
- 3 phase production separators (HP, MP, LP, 1st stage, 2nd stage, 3rd stage separators)
- 3 phase test separators
- L-L separators with a conductive phase present
- Electrostatic coalescers such as VIEC, dehydrators and desalters
- Oil/water settling tanks
- Any type of water treatment tanks
Measurement principle
The Sulzer iPhase™ profiler measures the electrical conductivity of the water/oil mixture surrounding each sensor.
Dispersed oil droplets are non-conductive compared to the surrounding water. The overall conductivity will therefore decrease with increasing concentration of oil. The iPhase™ profiler measures the oil-water interface, provides accurate measurements of water conductivity and thereby the oil in water profile inside hydrocarbon separators.
The conductivity is measured by setting up an electric field and measure the current flowing. The electric field is an induced field and is therefore very tolerant to deposits.
