半导体音响式钻孔水位测定仪是利用电极接触井液时,发出嗡嗡蜂鸣声来确定水位的一种装置。通常,用电极传感的各类装置,电极的制作是非常重要的。如图1所示:按电极的个数不同可分单极式和双极式两种,其中,单极式制作简单且使用较多。为适应在钻孔抽水的同时作水位测定,测试管的电极直径 Semiconductor acoustic borehole water level detector is the use of electrode contact well fluid, the buzz beep to determine the water level of a device. In general, the electrode sensing device, the electrode is very important. Shown in Figure 1: According to the number of different electrodes can be divided into two types of monopolar and bipolar, of which, monopolar production is simple and use more. In order to meet the drilling water pumping at the same time as the water level measurement, the test tube electrode diameter
