Claims (7)

1. Coriolis flowsensor, omvattende een behuizing en ten minste een Coriolis-buis met ten minste twee uiteinden die in een buisfixatiemiddel gefixeerd zijn, waarbij de flowsensor excitatiemiddelen omvat om de buis ten opzichte van de behuizing te laten oscilleren, alsmede detectiemiddelen om in bedrijf ten minste een maat voor bewegingen van delen van de buis te detecteren, met het kenmerk, dat de detectiemiddelen verend ten opzichte van de behuizing zijn opgehangen.
2. Coriolis flowsensor volgens conclusie 1, waarbij de flowsensor is ingericht om de detectiemiddelen in hoofdzaak op dezelfde wijze te laten oscilleren als de oscillatie van de Coriolis-buis ten gevolge van bewegingen van de behuizing, in het bijzonder door afstellen van de resonantiefrequentie en de dempingsratio van de verend opgehangen detectiemiddelen.
3. Coriolis flowsensor volgens conclusie 2, waarbij de resonantiefrequentie en/of de dempingsratio in hoofdzaak gelijk is/zijn voor de Coriolis-buis en de verend opgehangen detectiemiddelen.
4. Coriolis flowsensor volgens conclusie 2, waarbij de resonantiefrequentie en/of de dempingsratio in hoofdzaak kleiner is/zijn voor de Coriolis-buis dan voor de verend opgehangen detectiemiddelen.
5. Coriolis flowsensor volgens conclusie 4, waarbij de resonantiefrequentie en/of de dempingsratio voor de Coriolis-buis ongeveer 90% bedraagt/bedragen van die voor de verend opgehangen detectiemiddelen.
6. Coriolis flowsensor volgens conclusie 2, waarbij de resonantiefrequentie en/of de dempingsratio in hoofdzaak groter is/zijn voor de interne modus van de Coriolis-buis dan voor de verend opgehangen detectiemiddelen.
7. Coriolis flowsensor volgens een van de voorgaande conclusies, waarbij de Coriolis flowsensor verder is uitgevoerd zoals beschreven in NL 2011836.
