The MicroCorr Touch from HWM is
a standalone water leak noise
correlator with high visibility colour
touchscreen; it now features
Automated Filtering Intelligence
System (AFIS) software to make
accurate leak pinpointing quicker,
easier and more accurate.

Like most traditional correlators,
the MicroCorr Touch provides
default filter settings for a wide range
of different pipe materials and sizes.

While experienced users can
manually change the filter settings to
find the leak, this is often a time
consuming process involving
multiple correlations. With AFIS, the
MicroCorr Touch effectively builds
an expert user into the unit.

It works by automatically applying
multiple filter settings to determine
the best possible correlation result.
The system runs 55 different filter
combinations on the correlation data,
checking the quality of the result and
optimising the filter settings as
required, until the clearest, most
accurate result can be presented.

Working on live or pre-recorded
data, HWM says tests have shown
AFIS to improve leak pinpointing on
almost any pipe.
