Abstract

The present invention relates to an arrangement for detecting a delivery volume and/or a delivery flow, with a discontinuously operating pump (), at least one outlet line () and/or one inlet line (--) and a passive valve (--), which is arranged in the outlet line () or the inlet line (--) and which has a valve seat (--) and a valve head (--), the valve (--) being closed in a first position of the valve head (--) and being open in a second position of the valve head (--) of the valve (--). The arrangement according to the invention is defined by a sensor (--), by means of which values can be detected which indicate whether the valve head (--) is in the first or the second position, and by a computing unit () which is coupled to the sensor (--) and by means of which the volume delivered by the pump () and/or the delivery flow of the pump () can be calculated on the basis of the detected values of the sensor (--). The invention relates furthermore, to an extraction system for a plant protective with such an arrangement and to a method for detecting a delivery volume and/or a delivery flow of a discontinuously operating pump, which method can be carried out by this arrangement.
