Abstract

In a method to determine concentration of toner particles in a carrier fluid in a liquid developer system for a printer or carrier, a suspension of the carrier fluid in the toner particles is charged with an ultrasonic wave. A propagation time of the ultrasonic wave in the suspension is determined. A concentration of the toner particles in the suspension is determined from the propagation time. A system is also provided employing the above steps.
