Abstract
The invention discloses a micropump having heating elements in which an essentially pulsed operation of the heating elements occurs by means of a control unit. The pulsed operation of the heating elements enables an exact control of the flow rate. With the aid of the control unit it is possible to keep the flow rate constant over a long period of days or to change the flow rate rapidly and precisely.
