The development of ultrasonic flowmeter for very low liquids flow rate

摘要

In this study, small disk ultrasonic transducers were zused to develop a very small ultrasonic flowmeter with a measuring pipe diameter of between 1.0 mm and 4.0 mm. The feasibility of using an ultrasonic flowmeter to measure a h quid flow rate of between] mL/min and 1 mL/min was investigated experimentally As the result, it was found that the flowmeter can be very useful for various industry
