2 Features & benefits Applications Low to high viscosity design for single or FSO's & FPSO's custody transfer multiviscosity metering application (Crude oil) Superior linearity and repeatability On Fiscal metering OIML R7 compliant metering (Crude oil, condensates) (PTB /Gosstandart N 86) Pipeline metering stations Counting start from close to zero flow, (Crude Oil, Refined products) thanks to the hall effect sensor which Tanker switches even at very low impeller terminals rotation speed. products, Petrochemicals) and Offshore loading (Crude / allocation offloading Oil, Refined Light alloy, stainless steel or titanium Storage management (Crude Oil, helical Refined products, Petrochemicals) rotor for corrosion superior protection. Helical rotor rounded front profile for meter performance stability when fibers or contaminants are present in crude oil. Tungsten carbide parts special design bearings for long life duration and debris self cleaning Pressure compensated, interchangeable measurement cartridge for easy site maintenance and downtime reduction. Special body materials are available (Duplex, Hastelloy, Inconel...) // Page LE Leaflet Low pressure drop

3 Because every details count Design All internal parts are designed and tested using the most advanced FEA & CFD tools, ensuring the most efficient development of every mechanical parts that can affect the turbine meter performances. Performances reliability Crossplates supporting the rotor are welded on the cartridge two parts system, this ensures a perfect bearing set alignment, thus, reducing the frictions, it contributes to a better measurement repeatability. Unlike other mounting systems, the measuring chamber can be removed and then reinstalled without the need of any further recalibration. Bearings tungsten carbide grade is properly selected to minimize the erosion even in harsh conditions such as sand contents in the hydrocarbons. Lubrication is done by the medium by means of small ducts embedded in the bearing pocket, this prevents the could increase the friction. // Page LE Leaflet accumulation of particles or paraffin that
