摘　　要：工业过程需要检测不同管路中流体流速的大小。针对传统的电磁流量计存在测量口径固定、安装不便的问题,提出一种基于超声波管道流体流速传感器检测原理的便携式管道流体流速自动检测装置,实现了对管道介质流速的柔性测量。便携式现场主机可以与上位机通过RS-232通信接口相连,实现对多台检测设备流速记录的保存和数据的分析,尤其适用于一些不宜直接接触测量的流体介质的流速测量。In industrial processes,it is necessary to detect the fluid velocity in different pipeline. In view of the insignificancy of traditional electromagnetic flowmeters ,i. e. , the fixed measuring bore and installation inconvenience, the detection principle of a kind of ultrasonic fluid velocity sensor for pipeline is put forward; and the portable automatic detection device for pipeline fluid velocity is designed to realize the flexible measurement of pipeline medium velocity. This portable host unit on - site can be connected to the upper machine via RS232 communication interface, in which the velocity data from multiple detection devices can be recorded, stored and analyzed. The device is especially suitable for some unfavorable direct contact measurement of fluid flow velocity measurement.
