AVL Fuel Mass Flow Meter and Fuel Temperature Control The AVL Fuel Mass Flow Meter and AVL Fuel Temperature Control combine high accuracy and excellent temperature stability even with short measurement times.
The AVL Fuel Temperature Control and the AVL Fuel Mass Flow Meter with a pressure control system patented by AVL, provide constant, adjustable fuel pressures and temperatures. This allows for reliable and easy utilization for engines sizes up to 600kW with state-of-the-art mixture preparation systems.
AVL Fuel Mass Flow Meter 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 flow, is a separate measurement variable 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 flow.
