MEASURING DEVICE FOR THE REAL TIME REGISTRATION WITHOUT CONTACT OF THE PROPERTIES OR QUANTITIES CHARACTERISING THE PROCESS FOR SEPARATING OR SPLITTING LIQUID VOLUMES OR LAYERS IN ROLLER GAPS OF PRINTING MACHINES

摘要

This invention relates to a method of and a device for the weighted measurement of quantities of liquid per unit area and/or the relative quantities of a liquid per unit area by means of an acoustic sensor. More particularly, the method permits the measurement of quantities of liquid and/or relative quantities of a liquid per unit area at the outlet of a nip formed by two rollers completely or partially covered by the liquid and/or liquid mixture concerned, the rollers rolling one upon the other and the layer of liquid in the nip being split at the nip outlet. Splitting of the layer of liquid occurs particularly in printing machines and glue applying machines, to which the invention can accordingly be applied.
