Abstract

Et apparat (10) og fremgangsmåte er tilveiebrakt som innbefatter en romlig rekke eller gruppe av ustabile trykksensorer (15-18) plassert i forutbestemte aksiale lokaliseringer X1 - XN anordnet aksialt langs et rør (14) for å måle hastigheten og volumetrisk strømningsmengde til en enkeltfase- eller multifasefluid (12) som har et ikke-neglisjerbart aksialt machtall og som strømmer i røret (14). Trykksensorene (15-18) tilveiebringer akustiske trykksignaler P1(t) - PN(t) til en signalbehandlingsenhet (30) som bestemmer hastigheten til lyd som forplanter seg ned og mot strømmen av fluidet (12) i et rør (14) ved bruk av akustisk romlig rekke- eller gruppesignalbehandlingsteknikker. Apparatet, som reagerer på den målte hastigheten til lyd som forplanter seg ned og mot strømmen av fluidet, bestemmer hastigheten og strømningsmengden til fluidet som forplanter seg gjennom røret.
