Principle
Turbulence created by gas or air forced through a small orifice generates ultrasonic sound. Ultrasonic sound occurs when the atmosphere leaks into a vacuum vessel or when a pressure vessel leaks to the outside atmosphere. Ultrasonic sound's frequency is related to the size of the orifice which ultrasonic sound passes through,but usually the frequency is about 40Hz. Ultrasonic sound is very directional, this directionality is
used to pinpoint the origin of the ultrasonic sound, the leak point.
Portable case and carton box, please see picture for more detail.
