Measuring Apparatus for Diameter & Charge of Droplets in Electrostatic Pesticide Spraying

Measuring the diameter and charge of a droplet by using sine alternating current field is based on that the path of charged droplet, which affected by electric force,gravity, floatage of air and Stokes force in sine wave field, is a sine curve, and the diameter and charge of the droplet can be found out by measuring the amplitude and wave length of the sine curve.
