FPS - Fluid Purity System
Sensorteknikk has developed a Fluid Purity System (FPS) for measuring/detecting contaminations in fluid. Experiments and tests have been carried out to demonstrate various combinations of fluids and the capability of detecting very small quantities (ppm). The system can be trained to distinguish between a composition of several fluids such as liquids, gas and solids. These features make the system very suitable for supervision and detection of environmental pollution in addition to various industrial applications. The system’s unique flexibility is the main advantage compared to competing systems.
The FPS is based more or less on the same measurement principles as the Well Flow Analyser (WFA) described under “Offshore”. This means that the information of the fluid’s composition is extracted into a readable way by advanced signal processing, which in principle consist of transforming acoustic energy from time domain to frequency domain and further statistical analyse through acoustic chemometrics.
The FPS system is developed and designed to measure and detect various forms of contamination in fluids, primarily water pollution from outlets of industrial processes, leakages etc. In addition the FPS system has been installed to detect oil in water and glycol contamination of water.
Further development of the system for different applications is still going on at our laboratories.
Figure to the right - An FPS prototype was in 1999 installed at Oslo Airports de-icing recirculation process, in order to measure concentration levels of de-icing liquids. The system works on high precision (ppm and % levels) and real time. This pilot installation had its own mini test/calibration flow loop for initial research and testing.
The FPS system is developed and designed to measure and detect various forms of contamination in fluids, primarily water pollution from outlets of industrial processes, leakages etc. In addition the FPS system can measure oil in water/water in oil down to a few ppm. A practical example is detection of water in oil hydraulics systems.
