Abstract
A liquid dispensing device (10) having a drop ejection device (12) including an orifice (18) adapted for ejecting drops (20) therefrom above a particular turn-on-energy, a turn-on-energy detection device (28) positioned to receive turn-on-energy information from said ejected drops as a function of energy applied to the drop ejection device, and a controller (40) that receives the turn-on-energy information and conducts a mathematical operation on the turn-on-energy information to determine a drop volume of the drops ejected.
