摘要: A system and method is presented for measuring the volume of an ink-jet droplet or relative volumes a plurality droplets using their electrical properties. In preferred embodiment single small capacitor array capacitors used to measure dielectric properties absolute drop are derived. alternative differences in determined. feedback circuit, such as one lock-in technique, may be automatically adjust subsequent volumes.
