Method and apparatus for detecting leaks in a liquid-containing tank
摘要
A method and apparatus are disclosed for detecting leaks in a liquid-containing tank. The method and apparatus employ an internal reference cell immersed in the liquid in the tank which contains a volume of the liquid isolated from flow communication with the liquid in the tank while having a surface which is exposed to the ambient conditions above the surface of the liquid in the tank. The level of the fluid in the tank and in the reference cell are monitored over a period of time. Level changes in the tank which do not correspond to level changes due to the temperature and evaporative effects observed in the reference cell are indicative of a leak in the tank.
