Air flow measuring device FLOWSONIX™ Air

ultrasonicmassprocess

AVL FLOWSONIX™ Air is the innovative measurement system for the measurement of air consumption that is fast, accurate and robust. The measurement system uses an ultrasonic transit-time differential technique to accurately measure air mass flow in the intake. It measures the acceleration of the sound pulse travelling with the air flow, as well as the deceleration of the sound pulse travelling against the airflow. By comparing the two results, the mass of air flowing through the intake can be accurately assessed, delivering measurement uncertainty of less than 1 % of the reading. Why You Need FLOWSONIX Air Air consumption is an important reference value in emissions certification; hence OEMs must ensure an accurate measurement process to meet increasingly stringent regulations. AVL FLOWSONIX Air features highly dynamic and precise bidirectional air flow measurement with a data rate up to 1 kHz. These unique capabilities enable AVL FLOWSONIX Air to measure highly dynamic engine behavior and even flow pulsations in the engine intake path can be resolved and measured bidirectionally. Thus, correct measurement of applications with possible reverse flows are guaranteed.
