>>>when something is not pressurized or under a vacuum, it won't leak.<<<

I'm no scientist (just married to one) but I beg to differ. A vessel does not have to be pressurized to leak! Gravity provides all the needed "pressure" ie: poke a hole in your car's gas tank and see if it leaks! In this type of case, the ultraphonic detector employs a signal transmitter to be inserted in the tank which broadcasts ultrasonic sound inside the vessel, and if a hole or crack is present, the sound will escape through the hole and be pinpointed by the detector.

In the case of a vacuum leak, it is merely a case of reverse pressure, where air rushes INTO the line or vessel instead of OUT. In this instance the detector hears the ultrasonic sound of the air rushing in at the source of the "reverse" leak (and permits pinpointing the source of the vacuum leak.

Structural cracks might be detected in some cases if you can place the sound transmitter on one side of the structure and "hear" it on the other side of the structure with the detector, I would think, because a structural crack could be "static" rather than "dynamic" (such as a pressurized leak) situation.

Any comments?
