Capillary structure of an LFE (Laminar Flow Element)
Such corrugated sheet metal strips are rolled tightly together and installed in measuring tubes. This creates arrangements with many thin, long channels. If air is allowed to flow through such pipes, the measured pressure drop is linear to the volume flow. In my company we develop and build measuring devices for the precise measurement of air quantities.
My picture shows that explore and technology can also provide interesting pictures
