Abstract

A damping tube-shaped bypass measurement section with protective maintenance features and continuous flow velocity scanning on absorptive filtration units in the nuclear engineering field is disclosed. The bypass measurement section comprises a tube-shaped bypass measurement section, having single or double elements, for absorption filters, featuring at least one shut-off device, and including an absorption layer thickness connected to the main filtration unit which is to be controlled or monitored, and provides for an equivalent absorption layer thickness.
