Abstract: The present disclosure relates to an inspection assembly (1) for inspecting the interior of a fluid filled pipe (100), such as oil and gas wells, production and workover risers and the like. The inspection assembly (1) comprises a sensor chamber (10) arranged in a sensor chamber housing (11) and a control chamber (20) arranged in a control chamber housing (11), the sensor chamber (10) and the control chamber (20) being directly or indirectly connected to each other. The sensor chamber (10) comprises three or more sensor assemblies (12) and the three or more sensor assemblies (12) are arranged around the circumference of the sensor chamber housing (11) in an essential helical sequence to receive sensor signals from the interior of the pipe (100).
