INTRODUCTION
Ultrasonic sound (20 khz to 100 khz) is generated by turbulence created by air or a gas forced
through a small orifice. Ultrasonic sound is very directional in nature and can be used pinpoint
the exact location of the leak point.
Leaking air or gas is generally considered to be viscous flow and as the flow velocity increases,
the frequency of the ultrasonic sound emitted will become higher. The ULD-300 amplifies and
converts these sounds to frequencies and levels that the human ear can hear.

ULD-300 Ultrasonic Leak Detector Operation
plug the headphone (hp-1) into the jack located on the left side of the ULD-300. 1.
Rotate the thumb wheel clockwise to turn the ULD-300 ‘on”. The Battery LeD will normally be 2.
a green color. if the LeD is red, the 9V battery must be replaced.
Set the range switch (x1, x10, x100) to x100

Rotate the thumb wheel clockwise to 10 4.
point the ULD-300 energized point the sensor horn in the direction where a leak is suspected. 5.
for surroundings with a high level of background noise use the parabola (pB-1).

for locations that you cannot point the ULD-300 directly at the leak, the Te-2 and TeA-1 can
