摘要： The method for detecting leaks in an above ground storage tank includes the step of first determining the level of water in the tank by establishing, in a container lowered into and resting on the bottom of the tank, a clean interface between water and a liquid hydrocarbon product in the tank which has entered into the container. Preferably the method includes an initial step of inserting a predetermined amount of water into the container before lowering the container into the tank. The method also includes sensing changes in conductivity along a line intersecting an interface between the liquid hydrocarbon product in the tank and water in the tank with a leak detector in a casing and establishing a clean interface in the leak detector to prevent debris at the interface in the tank from fouling the sensing of changes of conductivity. Further, the method of establishing a clean interface in the container or the casing includes lowering the container or casing which is substantially closed and which is provided with an opening at the upper end thereof into the tank until it reaches the bottom of the tank; opening an inlet/outlet opening in the lower end of the container or casing after it has settled on the bottom of the tank; and, allowing a clean interface to be established in the container or casing.
摘要翻译：用于检测上述地面储罐中的泄漏的方法包括以下步骤：首先通过在下降到并搁置在罐底部的容器中的容器中确定水和液体烃之间的清洁界面来确定罐中的水位已经进入容器的罐中的产品。优选地，该方法包括在将容器放入罐内之前将预定量的水插入容器中的初始步骤。该方法还包括检测沿着与罐中的液体烃产物和罐中的水相交界面的线的电导率的变化，并在壳体中具有检漏器，并在泄漏检测器中建立清洁界面以防止在界面处的碎屑该罐从污染导电性变化的感觉。此外，在容器或壳体中建立清洁界面的方法包括将基本封闭的容器或壳体下降，并且在其上端处设置有开口到罐中，直到其到达罐的底部; 在容器底部沉淀后，在容器或外壳的下端开口入口/出口; 并且允许在容器或套管中建立清洁的界面。
