The Multi Award-Winning Profiler™ GPS

The instrument of choice for real time critical process measurements

The Profiler™ GPS is the only nucleonic instrumentation designed to measure the vertical distribution of gas, foam, oil, emulsion, water and sand in real time at high resolution.

Unlike conventional technology, this patented instrument is a 'window' into the vessel to enable the operator to improve production throughput, reduce the number of unscheduled shutdowns and achieve significant cost savings.

Our instrument is field-proven in hundreds of installations, providing a separation solution for millions of barrels of oil per day worldwide. The instrument is installed into some of the most challenging and diverse applications, ranging from subsea oil and gas processing, to downstream refining.

The Profiler™ GPS enables you to accurately measure and control the distribution of fluids such as:

- The interface between water and oil or oil and gas
- The quality of separation
- The extent of foam build up
- The total liquid position
- The level of sand build up

Increase Production Throughput
The accuracy and reliability of the in strument results in minimal process upsets providing operator confidence for real time process optimisation.

Non-contact technology and zero moving parts help to achieve mean time between failures (MTBF) in excess of ten years resulting in minimal operator intervention.

Improve Asset Environmental Compliance
Accurate interface level measurements minimise oil in water counts and therefore reduces environmental discharge.

Designed and built to the highest safety and integrity standards The Profiler™ GPS is able to accommodate SIL2 trip and shutdown requirements whilst also providing accurate level and interface visualisation.

Benefits of The Profiler™ GPS

- Increases production throughput.
- Real time process optimisation.
- Reduces shutdowns and chemical additives costs.
- Improves asset environmental compliance.
- Low maintenance

Typical Applications

The Profiler™ GPS is suitable for use in:

- Subsea processing.
- Upstream separation vessels.
- Downstream desalting applications.
