Abstract

Fremgangsmåte og et apparat for å dempe et ultrasonisk signal som forplanter seg i veggen av et rør (104), idet apparatet omfatter minst én dempestruktur (132) for å feste minst én føler til veggen av røret, der minst én føler omfatter en senderkomponent (122) og en mottakerkomponent (124) for å sende og motta et ultrasonisk signal, der den minst ene dempede strukturen er knyttet til ytterveggen av røret for å dempe det ultrasoniske signalet som propagerer i veggen av røret og en prosess som avgrenser en konvektiv kant i k-?-planet som svar på de ultrasoniske signalene og bestemmer hellingen av minst en del av den konvektive kanten for å bestemme fluidets strømningshastighet.
