<p>A flow control apparatus and a program are disclosed herein. A flow control apparatus includes a piezoelectric element coupled to a valve element configuring a flow regulating valve and that works the valve element to regulate a flow, a driving circuit that applies a voltage to the piezoelectric element to drive the piezoelectric element, an accepting means for accepting a target flow, and an output means for outputting a signal corresponding to the voltage applied to the piezoelectric element to the driving circuit, to change the flow so as to coincide with the target flow. When the target flow is changed, the output means transiently outputs a signal corresponding to a voltage value different from a target voltage value corresponding to the target flow after the change, and then the output means outputs a signal corresponding to a voltage change converging at the target voltage value.</p> |
