Its contribution to higher testbed efficiency is assured by determination of fuel consumption with the highest precision in minimum measurement temperature stability and cooling power fulfill all actual requirements regarding transient and dynamic testing. MEASUREMENT PRINCIPLE The FuelExact™ exists in two version: one based on the PLU measuring principle and one based on the Coriolis measuring principle. For further information, please refer to page 76. APPLICATION AVL FuelExact™ covers applications from singlecylinder up to 2 500 kW engines in the field of engine research and development due to the high data rate of 20 Hz and the fast step response, the system is ideally suited to transient calibration methods that are increasingly applied in the field of engine development. The FlexFuel version expands the application range towards development tasks in the field of bio fuels. New and improved features consistently protect your investment. / 110 time. The application focus is engines up to 2 500 kW.
