    Abstract: A method for operating a device for dosed supply of a liquid, having a pump to deliver the liquid. The pump has an inlet and an outlet. An eccentric is arranged on the pump housing and a deformable diaphragm is arranged between a pump housing and the eccentric. The deformable diaphragm and the pump housing delimit a delivery path from the inlet to the outlet. The seal can be displaced along the delivery path by movement of the eccentric. A pressure sensor is connected to the outlet of the pump. A liquid is delivered by the pump. A time curve of the pressure at the outlet of the pump is monitored during delivery by the at least one pressure sensor. An angle position of the eccentric of the pump is detected using at least one characteristic feature of the time curve at the outlet.
