MULTIPATH CROSS-CORRELATION FLOWMETERS

V. Skwarek, V. Hans

Abstract

The ultrasonic cross-correlation flowmeter is not only a reliable measurement device due to recent improvements in signal processing; it can even be used for gaining further knowledge about the properties of turbulent flow. This paper shows as well considerations about fluctuations, measuring time and ergodicity as arrangements and necessities for multi path measurements. Results are used for averaging and first tomographic approaches for the visualization of turbulent flow.
