测流的方法多种多样,现常用的主要有缆道流速仪测流和超声波测流。横向积分法测流也是缆道测流法的一种,以横向运动的方式测算断面平均流速。它与积点法的主要区别在于收集资料的方式不同,积点法以静止的方式测得测点流速;横向积分法是利用缆道设备使流速仪保持在水下的预定水深,从一岸向另一岸匀速移动,在运动过程中测量流速。
There are a variety of ways to measure current, there are mainly used cable current meter flow measurement and ultrasonic flow measurement. The transverse integration method of measuring flow is also a kind of cableway flow measurement method, and the average velocity of cross section is calculated by means of lateral movement. The main difference between this method and the product point method is that it collects data in different ways. The product point method measures the flow rate of the measuring point in a stationary manner. The horizontal integration method uses the equipment of the cable way to keep the flow meter in the predetermined water depth, Move to the other side at a constant speed and measure the flow rate during the movement.
