摘要：
Improving the accuracy of the flow rate of a valve in a fiuidic delivery device in which a desired flow rate may be achieved by varying the duty cycle of the valve. 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 fiuidic parameters that impact on the flow rate delivery by the valve and differ among fiuidic delivery devices is compensated to optimize the flow rate accuracy.
