1.1 General
The new HLE 5000/500 leak locator comprehensively deals
with finding leaks in pipe networks for the supply of drinking
water. The equipment can of course be used on other pipe
systems, provided that the liquid comes out of the pipe under
pressure and that the resulting noise carries to the surface of
the ground. With the HLE 5000/500 it is possible to both pre-
locate and to pinpoint the location of the fault. With a special
Dual Segment Analysis (DSA) display, both the minimum
value of the constant noise as well as the leak noise can be
recognised. With the “Mute” option, used when moving the
ground microphone, a new minimum display results. A
comparison of the measured values is thus always possible.
In the “HISTOGRAM” function, each measurement location is
stored, one by one.
This equipment is the first instance where computer
supported reduction of extraneous noise is used, where
impulse type disturbances are acoustically suppressed.
Preferably, only constant noise (as produced by a leaking
pipe) is displayed as a minimum value.
When locating plastic pipes with the assistance of an RSP3
“pipe pecker”, picking up impulses is then desirable and
improves the results. For this reason, the HLE 5000 has a
special pipe location mode that is activated, after switching
on, by pressing the symbol button.
Another important function of the HLE 5000 is the noise level
recording with which the course of the development of the
noise is shown on the LCD display as a graph over time.
