Wheel probes

OSTI ID:6336457
By employing a flexible diaphragm in the wall of the fluid chamber, an improved ultrasonic wheel probe for internal pipe inspection avoids the loss of the liquid acoustic coupling medium that can occur in high-pressure environments. This diaphragm deflects in response to pressure changes thus balancing the liquid pressure with the pressure of the gas in the pipe.
