/ 135 AVL Fuel Mass Flow Meter and Fuel Temperature Control Regarding fuel consumption measurement, the mass ��ow measurement system AVL Fuel Mass Flow Meter and Fuel Temperature Control uses a Coriolis sensor optimized by AVL and supplies the engine testbed with fuel of the highest temperature stability. A pressure control system patented by AVL provides constant, adjustable fuel pressures and allows reliable and easy utilization with state-of-theart mixture preparation systems. The FlexFuel version is applicable to bio fuels and, thus, provides investment safeguarding for future development tasks. MEASUREMENT PRINCIPLE The fuel passes through a U-shaped tube which vibrates at its natural frequency. This frequency is proportional to the fuel density which, in addition to the mass ��ow, is a separate measurement varia��le and, thus, allows for the output of volumetric measurement values. The time lag of the vibration frequency C1 to C2 is proportional to the mass ��ow. APPLICATION ��iven its precision of 0.12 �� and direct mass ��ow measurement capability, the AVL Fuel Mass Flow Meter with Fuel Temperature Control can be used on all engine and chassis dynamometer test beds in the fields of research, development and production. The measurement system can be used universally for different engine sizes from single- cylinder engines up to 600 kW large-scale engines and for state-of-theart mixture preparation systems and test cycles. BENEFITS AT A GLANCE • Shorter measurement and testing times due to precise fuel temperature control within +/– 0.02 °C • The patented AVL pressure control allows for a universal application, in line with the requirements of state-of-theart measurement methods and injection systems �� Increased test��ed efficiency due to reliable measurement operation, integrated maintenance displays and detailed diagnosis functions • With numerous options, a broad spectrum of applications is covered FUEL CONSUMPTION MEASUREMENT Sensor C1 Coriolis Force Sensor C2 Signal Density Mass Flow C1 C2 t Flow
