Abstract An ultrasonic flowmeter for liquid based on reticulated acoustic path arrangement is developed. The layout of ultrasonic transducers based on the principle of directivity, and a 16-channel ultrasonic flowmeter formed by 16 transducers in DN100 diameter is realized by using one transducer to transmit the ultrasonic wave and the other two transducer to receive. Through the intrinsic errors test and repeatability test under normal installation condition, the accuracy level of 0.2 is achieved, and the repeatability is less than 0.6‰. In addition, the flow field adaptability and stability of the ultrasonic flowmeter based on reticulated acoustic path arrangement are verified through the intrinsic errors test of indication after the Angle installation and flow disturbance.

Key words： metrology reticulated acoustic path arrangement ultrasonic flowmeter directivity flow disturbance
