按傳感器原理分浮子式、跟蹤式、壓力式和反射式等。水位記錄主要有：記錄紙描述，數據顯示或打字記錄,穿孔紙帶,磁帶和固體電路儲存等。水位計的度一般在1～3厘米以內，制造的水位計的記錄周期有1天、30天和90天等。走時誤差,機械鐘為2分/日，石英晶體鐘小于5分/月。分類浮子式水位計其原理是由浮子感應水位的升降。有用機械直接使浮子傳動記錄結構的普通水位計，有把浮子提供的轉角量轉換成增量電脈沖或二進制編碼脈沖作遠距離傳輸的電傳、數傳水位計，還有用微型浮子和許多干簧管組成的數字傳感水位計等。應用較廣的是機械式水位計。應用浮子式水位計需有測井設備，只適合于岸坡、河床沖淤很小的低含沙量河段使用。測井見圖1。如果VS的控制極沒有輸入觸發脈沖Ug，VS仍然不能導通，只有在U2處于正半周，在控制極外加觸發脈沖Ug時，晶閘管被觸發導通。畫出它的波形（c）及（d），只有在觸發脈沖Ug到來時，負載RL上才有電壓UL輸出。Ug到來得早，晶閘管導通的時間就早；Ug到來得晚，晶閘管導通的時間就晚。通過改變控制極上觸發脈沖Ug到來的時間，就可以調節負載上輸出電壓的平均值UL。在電工技術中，常把交流電的半個周期定為180°，稱為電角度。這樣，在U2的每個正半周，從零值開始到觸發脈沖到來瞬間所經歷的電角度稱為控制角α；在每個正半周內晶閘管導通的電角度叫導通角θ。很明顯，α和θ都是用來表示晶閘管在承受正向電壓的半個周期的導通或范圍的。
