Abstract
A system for controlling the formation of droplets in a fluid stream includes a continuously flowing fluid stream through a droplet generator. The system further includes both a sinusoidal drive voltage at a predetermined frequency and a plurality of piezo electric crystals for causing the droplet generator to resonate and inducing a series of uniformly sized droplets to separate at regular intervals from the droplet generator. Finally, the system includes a drive signal for adjusting to the resonance of the droplet generator to control the formation of the droplets. The drive signal is applied to the crystals by a digital phase lock loop.
