METHOD OF CONTROLLING ULTRASOUND SPRAYING Russian patent published in 2012 - IPC B05B17/06 

FIELD: process engineering.

SUBSTANCE: invention relates to chemical industry and electronic industries, etc, and may be used for making ultrasound sprayers. Proposed method comprises controlling amplitude of current representing difference between current in oscillation system transducer piezoelectric elements and capacitive component of said current caused by intrinsic electrical capacitance of piezoelectric elements. In comprises also increasing or decreasing amplitude of voltage fed from electronic generator to piezoelectric transducer proceeding from comparison of fluid impedance values controlled by current and voltage, said fluid being sprayed at mean arithmetic impedance measured prior to spraying, and piezoelectric transducer intrinsic impedance. Voltage is increased or decreased unless measured impedance equals means arithmetic valued between that measured prior to spraying and said intrinsic impedance.

EFFECT: higher efficiency.
