Method of confirming the presence of a leak in a liquid storage tank |
摘要 |
Method of confirming the presence or absence of leaks in a liquid storage container, particularly in partially filled underground storage tanks, subjected to partial vacuum for the purpose of testing the tank for the presence of a leak in the area above the liquid using a hydrophone or microphone either positioned in or attached to the container to detect the sound produced by the ingress of fluid into the container as a result of the vacuum. The ingress of fluid is confirmed by recording and observing the vacuum pump on/off cycles, the on/off cycles for a leaking container being distinguishable from the on/off cycles for a non-leaking container.
