JetMix System with Integrated Water-in-Oil Measurement

 

A Jiskoot JetMix system with integrated water-in-oil measurement was selected to provide representative water content analysis for a major North Sea Floating Production, Storage and Offloading (FPSO) vessel.

 

Chosen because it is the only technically viable solution, the JetMix system provides fully mixed flow to the water-in-oil monitor whilst creating a negligible pressure drop ensuring that gas does not 'flash-off' from the high RVP condensate liquid.

 

The JetMix guarantees mixing in the 16in line according to the ISO3171 standard required for accurate water measurement. The water-in-oil monitor is mounted as part of the mixed JetMix loop ensuring the measurement is representative of the whole pipeline contents.

 

The type of power mixer used is designed to maintain the fluids in a liquid state and ensure they are homogeneous for fiscal analysis or sampling. It comprises a 'quill' take-off point, bypass loop, a pump and motor unit to externally provide the mixing energy and a nozzle assembly through which the process fluid is injected back into the pipeline to provide mixing ...

Automotive Pedestrian Protection System

 

Passive safety on the road gains increasingly more relevance with each passing year, as the lives of drivers, passengers, and pedestrians are given top priority. Automotive pedestrian protection systems are currently being introduced in the European Union (EU) with the goal of reducing the number of car accident injuries and fatalities among vulnerable road users, such as pedestrians. It is by a voluntary agreement between the EU and the ACEA, the European Association of Car Manufacturers, that the automotive sector undertakes the task of improving the front end design of their vehicles in order to meet such regulations.

 

The IEE Protecto® system is able to fulfill these needs by offering high reliability, design flexibility and easy adaptability at an attractive price. Protecto® is a complete pedestrian protection system that enables car manufacturers to meet the new European and Asian regulations by reducing head injuries, in car impacts that involve pedestrians. Protecto® includes a robust sensor unit that is easily integrated into the bumper system and is able to very quickly detect the impact of an object to the bumper area. Also a part of Protecto® is an electronic control unit that includes a proprietary algorithm developed by IEE. This algorithm is able to classify the object on the basis of measured values and take the necessary decision. This algorithm is able to differentiate between the various impacting objects, thereby avoiding incorrect hood activations. The electronic unit can also be integrated into an already existing ECU (for example the airbag control unit) ...
