New measurement methods and demands for increased test bed efficiency have resulted in a clear trend toward continuos fuel consumption measurement.
The AVL Fuel Mass Flow Meter acknowledges this trend and, with its direct mass flow measurement at 0.12% accuracy, it can be used on all engine and chassis dynamometer test beds. The new second generation AVL Mass Flow Meter is more universally applicable to a variety of engine sizes, engine injection systems and testing cycles.
Improved software architecture makes for simpler connection to automation systems, and extended diagnostic functions ease fault tracing through the entire measurement and supply network. Integrated statistical evaluation methods and plausibility checks permit shorter measurement times and a consequent reduction in time on the test bed.
The new AVL Fuel Mass Flow Meter features high reliability and ease of application to the latest injection systems like gasoline and diesel injection.
This is achieved through the use of a specially developed pressure control system that makes vehicle-like conditions possible on the test bed, and prevents undesirable pressure build-up in the measurement circuit. The measurement of any return flow avoids errors in the total value (e.g. cycle consumption).
A unique feature of AVL fuel consumption measuring systems is the built-in accuracy check and calibration, which offers confidence for a day-to-day operation and cuts operating costs.
