Method and device for the gravimetric and in-series distribution of solution

Abstract

A method and device for the gravimetric and in-series distribution of a predetermined quantity of a solution. The device has a delivery mechanism for delivering a solution, a weighing mechanism and a mechanism for measuring an operating value to establish a setpoint value of the delivery mechanism during a calibration step during which the weighing mechanism is used for the delivery of a predetermined quantity of solution. The device also has an actuating mechanism to actuate the delivery mechanism with the setpoint value to carry out one or more distribution steps with the delivery of the predetermined quantity of solution without using the weighing mechanism.
