The invention relates to a method for controlling the optimal dosing quantity Dopt of treatment chemicals to be introduced into continuously flowing fluids that are to be treated. The aim of the invention is to provide a method which is self-calibrating and which is characterized by a most economically possible use of treatment chemicals. In addition, the method should, to the greatest possible extent, be unaffected by a process-related contamination or by a zero shift of the measuring probe. To these ends, the invention provides a method with which the dosing quantity (D) is periodically changed by a predeterminable dosing quantity change DELTA Di at an interval of a predeterminable clock time DELTA ti.

In einem Verfahren zum Vermischen zweier Ausgangslösungen zu einer Arbeitslösung mit exakt bekanntem Mischverhältnis, wird vorgeschlagen, daß die beiden Ausgangslösungen im ersten Schritt einer Grobvermischung mit einem Mischverhältnis in einem vorgebbaren Bereich unterworfen werden, dann im zweiten Schritt der Wert eines internen Parameters der Arbeitslösung bestimmt wird, dessen Wert in den beiden Ausgangslösungen bekannt und deutlich unterschiedlich ist, und im dritten Schritt aus dem gemessenen Wert des internen Parameters das exakte Mischverhältnis der Arbeitslösung bestimmt wird.
摘要:
An apparatus and process for automatically and rapidly making a paint having the color values of a standard paint; a computer is used which is connected to and controls a multiplicity of metering pumps that are each individually connected to a supply of components used to make the paint such as binder solution, solvent and colorants; the components are accurately metered into a mixing vessel and mixed, paint is circulated through a recycle loop attached to the vessel, the loop contains a cell having a viewing window through which the paint is pumped, a colorimeter views the cell and determines the color values of the wet paint and feeds these values back to the computer which compares the values to values of the standard paint and calculates the amount of colorant to be added and signals the metering pumps to add colorant, the process is repeated until the paint is brought within the tolerance values of the standard paint.
