Title: Ultrasonic testing device having an adjustable water column

Patent ·
OSTI ID:1213455
; ; ;

An ultrasonic testing device having a variable fluid column height is disclosed. An operator is able to adjust the fluid column height in real time during an inspection to to produce optimum ultrasonic focus and separate extraneous, unwanted UT signals from those stemming from the area of interest.
