Abstract
A computer with a proper program generates a phased array sequence of signals. In a pulser with delays, the signals are fed through a multiplexor into a water wedge that is attached to a valve being tested. For a sequential operation of the valves from the open to the closed position, ultrasonic signals are transmitted through the fluid contained in the valve and reflected back through piezo-electric crystals to the multiplexor. By summation and merger of the signals, an image can be developed of the operation of the valve to determine if the valve is operating properly. By use of the water wedge, the top plate of the valve appears to disappear because the water wedge has the same refractive angle as the fluid contained in the valve.
