Contrast to piezometer, standpipe i

Contrast to piezometer, standpipe is used to measure the water level directly and hence shorter response time is expected. The configuration of standpipe is similar to that of piezometer, except that the bentonite seal/ grout are replaced by sand/ gravel. Typical standpipe arrangement is as follow:

對比測壓，立管是用來直接測量水位，並因此更短的響應時間的預期。豎管的結構是類似的測壓的，不同的是膨潤土密封/水泥漿被砂子/礫石替換。典型豎管安排如下：

與壓電計相比，立管用于直接測量水位，因此預計回應時間較短。立管的配置與壓電計結構相似，只不過膨潤土密封/灌漿被砂/礫石取代。典型的立管佈置如下：
