How it works:
An immersion pulse-echo technique is used. The Ultrasonic transducer is housed in a turbine head with a rotating 45° mirror. The turbine assembly is centered in the tube axis. These pulses are emitted parallel to the tube axis and are reflected by the 45° mirror so that they are directed radially into the tube wall. The reflections from both inner and outer tube wall follow the same path to the transducer. The time interval between the first wall echo (front) and second wall echo (back) is the measure of wall thickness. As the mirror rotates, the ultrasonic beam sweeps the entire circumference of the tube wall. Turbine speed and PRF are adjustable to allow inspection pulls up to 5 mt per minute.
