Abstract :
This paper presents a high precision ultrasonic flow meter, designed especially for thin pipe. As thin pipes have a diameter less than 10 millimeters, conventional clamp-on ultrasonic flow meter is not appropriate for this kind of application. A special shape of pipe is designed, accompanied with customized transducers. To analysis the inner flow field, Computational fluid dynamics (CFD) is used to simulate the velocity distribution of the liquid. Finally, a preliminary experimental result of the flow meter is given.
