摘　　要：本文简述了超声波流量计的时差法测流原理,介绍了流速仪法测流流量计算的方法。通过超声波法与流速仪法实际测流比较,得出超声波流量计测量精度高,适用性强,不影响渠道水流状态,可直接与微机结合,实现水情数据的实时监测和实时传送,可以作为准确测量明渠流量的一种方法加以推广。This paper introduced the flow measuring principle of time - difference method of ultrasonic flow meter and the flow calculating method in flow measurement with velocity instrument. Through the practical flow measuring Comparison between ultrasonic and velocity instrument, that the ultrasonic flow meter possesses higher precision, and Stronger applicability than the velocity instrument can be concluded. Moreover, ultrasonic flow meter does not affect the flow state in open channel and realizes the real - time monitoring and the real - time delivering of hydrological data. So, it can be promoted properly in the flow measurement of open channel as an accurate method.
