The flow rate of fluid delivery from the valve over its lifetime is stabilized by minimizing the voltage OPENING time of the valve to account for valve and piezoelectric actuator drift. Also, the valve OPENING time of one or more fluidic parameters that impact on the flow rate delivery by the valve and differ among 10 fluidic delivery devices is compensated to optimize the flow rate accuracy. 13/10/09,va 18299 speci.doc.361/15 FIG. 1 a 10 50 12
