Trapped air and gas pockets in pipelines can have significant detrimental impacts on the operation of the system such as broken pumps, valves and pipes, resulting in costly maintenance, repair and replacement. Gas pockets in rising sewer mains are highly corrosive and cause localised deterioration of the main and premature failure.
g-CAT™ employs an advanced algorithm based on the speed of a transient signal to determine the locations of the air pockets with a +/- 10 m accuracy. g-CAT™ is applicable for all metallic, concrete and AC pipes.
