Ultrasonic Transducer Delivery Tool

Stennis Space Center has the need to measure the inner wall thickness of cryogenic storage tanks without entering the inner tank of the double-walled vessels. It was proposed that an ultrasonic probe be inserted through access points in the outer wall of the vessel and delivered to the inner wall of the...
