  流速计、液位计安装位置的选择

流速计、液位计的安装位置要尽量选择在渠道或河道比较平直的地段, 尽量躲开闸门、弯道、进水口/出水口、上下坡道处,直渠段要有一定的长度,直渠段上下游的长度最好大于 10 倍的渠宽,这样测量段的水流分布会相对稳定和均匀,测量数据就会更加准确。流速传感器安装在渠道的边壁上(如果没有泥砂淤积问题,安装在渠道底部也可),垂线位置最好在水深的 60%处(固定水深),方向标示指向水流下游,保证流速传感器平行于水流方向。液位计的安装点要尽量靠近流速传感器的安装位置,液位计的安装要垂直于水面,(非接触液位计测口平面到渠底的距离要和液位计的安装高度相一致,压阻水位计量程和显示仪内部水位计量程一致)。

布线

智能化明渠流量测量系统的所有连接线要尽量短,尽量避开动力线,做好连接线的防水、防潮、防断、屏蔽处理,保证接线的正确无误。
