摘要研制了一种基于网状声路布置的液体超声流量计。超声换能器的布置方式基于超声换能器指向性原理,采用1支换能器发射2支换能器接收的换能器布置实现了DN100口径共计16支换能器形成的16声路超声流量计。通过正常安装情形下的示值误差测试和重复性测试,实现了0.2级准确度等级,重复性小于0.6‰。另外,通过转角度安装、施加流体扰动后的示值误差测试,验证了基于网状声路布置的超声流量计的流场适应性和稳定性。

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
