目前,国内用于测定抽水井孔内的地下水位的仪器类型甚多,但几乎都有着一个共同性的缺点。即受到井壁流水或漏水现象的干扰,造成水位误测。虽然无感应水位计能够消除这种干扰,但因结构较复杂,国内未大批生产而难以普遍推广。为了提高地下水位的测定精度,克服井壁漏水的影响,我们研制出了水位计无干扰探头。 At present, there are many types of instruments used to measure the groundwater level in the wells of pumping wells, but almost all have a common disadvantage. That is to say, it is disturbed by the phenomenon of flowing water or water leakage in the wellbore, causing misdetection of the water level. Although non-inductive water level gauges can eliminate this kind of interference, due to the complex structure, there is no mass production in the country and it is difficult to generalize. In order to improve the accuracy of groundwater level measurement and overcome the effects of water leakage from the well wall, we have developed a water level meter interference-free probe.
