Nonintrusive (Noninterfering) Ultrasonic Techniques to Measure Gas Mass Flow Rates

Abstract

An analytic and experimental effort was conducted to determine the range of applicability of ultrasonic flowmeters for gases, and in particular, to determine the optimum nonintrusive ultrasonic flowmeter design for the wind tunnel. This effort included evaluations of six types of ultrasonic flowmeter approaches: transmission, reflection doppler scatter, beam drift, correlation, noise, and vortex shedding. For a class of duct applications represented by the tested facilities, it was concluded that a transmission measurement would be optimum. A discussion is presented of this system.
