Abstract:
An ultrasonic squirter couples transducer emitted ultrasonic waves with a structure for ultrasonic testing. The squirter has a tubular body with an outlet on one end and an inlet spaced from the outlet for delivering a flow of liquid through the body to the outlet. The transducer mounts in the body in a position for transmitting and receiving ultrasonic waves through the liquid that passes through the outlet. A nozzle secures to the outlet for discharging the flow of liquid against the structure. A ring locates at the outlet of the body just downstream from the transducer. The ring and nozzle are of an elastomeric material containing metal oxide particles to absorb unwanted sound energy.
