4.0 LEAK SOUND WAVES
The characteristic sound produced by a leak is a form of energy that
results from fluid escaping under pressure. This sound energy travels
as sound waves down the pipe in both directions from the leak site.
These waves are carried through the piping fluid and through the walls
of the pipe. Therefore, in order to detect leak sound, a device must be
able to detect the leak sound vibrations in the pipe wall or alternatively
on pipe fittings (valves, hydrants, etc.).
5.0 TRANSDUCER
Sound Pick-Up Transducers are the devices used to detect the leak
sound by generating an electrical signal in response to a mechanical
vibration. The standard transducer available for use with the S30 is:
AX-80 Transducer (accelerometer)
