tool is deployed entirely within a utility pig, and thus
is able to inspect the pipeline as part of a routine cleaning or gauging
opertion . SAAM uses the cleaning pig itself as its
carrier and sensor, and by recording the behavior of the pig as it
travels down the line, is able to identify, locate and monitor a wide
range of features and conditions within a line.
SAAM unit consists of a 316SS pressure casing container
a processor stack, memory card, battery pack, power supply card and
instrumentation. The SAAM can be supplied with a range
of sensors, including a differential pressure cell, absolute pressure
cell, temperature sensor, accelerometer, and vibration sensor.

EGP (Electronic Gauging Pig)
EGP provides a technologically advanced method by which
to gauge a pipeline, new or old. Based on the standard SAAM
hardware, the EGP provides the aded capability of rapid turnaround
of key information from the data, within a number of hours or days.
By retrofitting SAAM EGP into a traditional gauging
pig, the user can add significant value to the standard gauging process.
SAAM EGP offers the following benefits:
diagram shows a standard section of pipe, with a dent in it. The
pig will be forced to squeeze as it passes through this section.
the pig initially hits the dent, it will be impeded, causing the
pressure to build up behind it. This results in an increase of DP.
As the pig is then forced passed the intrusion, the DP returns to
its normal level.
the pig is impacting with the dent, the normally low background
vibration is increased as it bumps its way passed. The vibration
then returns to normal.
the pig hits the dent, it is momentarily showed down. As it is released
passed the dent, it then momentarily accelerates, back to its previous
