A nebulization control system for an ultrasonic nebulizer comprising a variable pulse oscillating circuit, an ultrasonic vibrating circuit and an ultrasonic vibrator is described. The ultrasonic vibrator is caused to vibrate alternatingly between a high level which is sufficient to nebulize a fluid and a low level which is insufficient to nebulize the same. The ratio of duration of the high level to the low level and/or the amplitude of vibration at the high level is variable. This arrangement permits a precise control of nebulization quantity and assists in the production of a fine, uniform mist of fluid.
