摘要
由于广泛使用的明渠呈开口形状,且水渠中的水位高度又是一个变化值,这给明渠的水流量测量带来很大困难.本文介绍了一种带流速自校正的智能明渠流量装置,能根据所测量明渠中水的液位值,自动调整流速传感器在水中的高度,并自动校正出整个明渠两个截面的平均流速,从而实现明渠水位高度、瞬时流量和累计流量的准确测量.
Due to the wide spread use of the channel is in an opening shape,and the water level in the channel height is a changing value,which brings great difficulties to open channel flow measurement of water. This paper introduces a kind of intelligent open channel flow device with velocity of self calibration,according to the water level value,automatically adjust the height velocity sensor in the water and correct the the average velocity in two sections of open channel,it realizes the accurate measuring of water level,instantaneous flow and cumulative flow in open channel.
