Abstract
The device for the continuous monitoring of the correct proportioning and mixing of at least two fluids comprises a static or dynamic mixing device ending in a nozzle, wherein within the nozzle, the cross-sectional area of the stream or flow after the last mixing element of the static mixing device or at the end of the dynamic mixing device, as seen in the direction of flow, is substantially reduced compared to the cross-sectional area of the mixing part of the mixing device. This reduction is realized either by an internal volume displacing means or by reducing the diameter of the nozzle after the last mixing element of the static mixing device or at the end of the dynamic mixing device, and the nozzle being at a maximum transparency at the point of scanning. Such devices allow a more accurate monitoring since the greatest possible part of the stream of the mixed material can be more easily viewed or sensed.
