Ultrasonic flow meter for measuring mass flow rate in automobiles has two ultrasonic transducers whereby in main flow direction turbulator is arranged on ultrasonic transducers which produce longitudinal vortices in adjacent area

摘要

Ultrasonic flow meter has laminar fluid (112) flow in the main flow direction (210) whereby ultrasonic transducers (116) are arranged under 90[deg] to the main flow direction for emitting and receiving ultrasonic waves. The turbulators (212) are arranged on two ultrasonic transducers in the main flow direction which produces longitudinal vortices (510) in area adjacent (122) to ultrasonic transducers.
