Traditional transducer emit from bottom / side to top with cavitation in single way
-- Tubular Immersible System --
Tubular transducer emit 360º ultrasonic waves and waves will be refracted when they touch SUS water tank wall which will expand the cavitation and crisscross its directions to make the ultrasonic full of intensive in the water.
