Efficient and professional fuel consumption measurement for steady state and dynamic test cycles

AVL FueLexAct MAss FLow & PLu

Do you need a measurement device which is also de-signed for future requirements? Do you want a measure-ment device which can be adjusted to different engine types and injection systems in an easy and safe way?

The FuelExact is a high precision fuel consumption mea-surement system. It ensures higher testbed efficiency by determining fuel consumption with highest precision and minimum measurement time.

The application focus is engines up to 2500kW. Highest fuel temperature stability and cooling power fulfill all actual requirements linked to transient and dynamic testing.

Your benefits:• High flexibility for adaptation to different injection systems

as well as a wide range of engine power up to 2500kW• Highefficiencyonthetestbedbyuniquerepeatability
