How it works:

A robot, equipped with ultrasonic transducers, is inserted into the tank through a manhole on the tank roof. As soon as it reaches the bottom of the tank it starts the inspection, the sonar system helping it to navigate and to avoid obstacles like roof supports. The robot is connected with a number of transceivers which are attached outside around the tank to determine the exact location of the robot.

All results are directly transferred outside to the control unit for analysis and report generation.
