Abstract

A method and an apparatus for a repeatable dosing or metering of fluids and in particular liquids in a selectable and reproducible amount in which the fluid amount to be dosed is learned in a dosing operation effected manually once and stored in a retrievable way; the apparatus comprises a fluid line 2 for a fluid 1 including a fluid inlet 3 and a fluid outlet 4 between which a shut-off device 7 controlled by a control unit 8 is provided, an operation 5 and a memory input 9 a learning mode is initiated and that by once pre-dosing a corresponding quantity information is stored and that by operating the memory input 9 a dosing mode is initiated in which the fluid amount corresponding to the stored quantity information is dosed by the shut-off device.
