测量地下水位深度并了解其动态,在实践中有很大意义.目前常用下端坠有重物的测绳掉人观测并测量地下水位.这一方法的优点是简单易行,但准确度稍差(尤其当水位很深时〕.国外有用“电水位计”测量地下水位的报导.用“电水位计”测地下水位的装置如图1所示.所用电池为锌锰干电池,即普通手电筒照明用者,其额定电压为
Measuring the depth of the groundwater level and understanding its dynamics is of great importance in practice.Nowadays, ropes with heavy weights are often used to observe and measure the water table.The advantage of this method is that it is easy to implement, but its accuracy is slightly less (Especially when the water level is very deep.) Foreign useful “electric water level gauge” groundwater level measurement report. “Water level gauge” groundwater level measurement device shown in Figure 1. The battery is zinc-manganese batteries, that is, ordinary flashlight lighting Users, the rated voltage is
