  流速計、液位計安裝位置的選擇

流速計、液位計的安裝位置要盡量選擇在渠道或河道比較平直的地段, 盡量躲開閘門、彎道、進水口/出水口、上下坡道處,直渠段要有一定的長度,直渠段上下游的長度最好大于 10 倍的渠寬,這樣測量段的水流分布會相對穩定和均勻,測量數據就會更加準確。流速傳感器安裝在渠道的邊壁上(如果沒有泥砂淤積問題,安裝在渠道底部也可),垂線位置最好在水深的 60%處(固定水深),方向標示指向水流下游,保證流速傳感器平行于水流方向。液位計的安裝點要盡量靠近流速傳感器的安裝位置,液位計的安裝要垂直于水面,(非接觸液位計測口平面到渠底的距離要和液位計的安裝高度相一致,壓阻水位計量程和顯示儀內部水位計量程一致)。

布線

智能化明渠流量測量系統的所有連接線要盡量短,盡量避開動力線,做好連接線的防水、防潮、防斷、屏蔽處理,保證接線的正確無誤。
