Abstract

The invention refers to a metering pump system comprising at least one metering pump (2) provided for connection to at least one exchangeable liquid container 16 via a suction line 10, and a control device 18, 24 for control of the at least one metering pump (2) wherein the control device 18, 24 is configured such that it records the total volume pumped by the metering pump (2), compares the recorded total volume with a nominal volume of said liquid container 16 and starts an action if the recorded total volume exceeds the nominal volume by more than a predefined threshold, and a method for controlling such metering pump system.
