Abstract

Two-phase flow measurement is a challenging task for ultrasonic flowmeters. This paper introduces a more stable and robust ultrasonic flowmeter technology, which can better cope with liquid flow with enriched gas bubbles. The flowmeter uses broadband ultrasonic transducers and multi-frequency digital signal processing to enhance the signal to noise ratio under gas bubble interference. The same flowmeter can thus measure both dirty and clean flows, widening its application area. An experimental flow system is set up to test the new technology with a benchmark flowmeter.
