54,907 ABSTRACT OF THE DISCLOSURE An ultrasonic cleaning apparatus and method is provided for a venturi flow nozzle which is mounted in a pipe having fluid flowing therethrough. The apparatus include a plurality of ultrasonic transducers mounted in openings provided upstream of the venturi flow nozzle inlet. The transducers transmit ultrasonic waves directly into and thereby excite the fluid flowing through the venturi flow nozzle and create cavitation which cleans the nozzle. Additional transducers are preferably provided in the throat area of the venturi flow nozzle. In alternative embodiments, the transducers are mounted in high and low pressure taps associated with the venturi flow nozzle such that the transducers directly transmit ultrasonic waves into fluid flowing into the high and low pressure taps. The transducers may be mounted flush with the interior of the pipe or venturi flow nozzle, or the transducers may be mounted at a position spaced therefrom in the high and low pressure tap piping.
