Abstract

Oppfinnelsen gjelder et differensialtrykkutstyr (4) og en gassmåleranordning (1) for mer nøyaktig måling av en gassleveranse (6a) med en gassmåler (2). En gassmåler (2) anordnet i en omføringsledning (3) og med et differensialtrykkutstyr i gassledningen (5), for måling av volumstrømmen (dV/dt, 6a) gjennom gassledningen, er kjent. I henhold til oppfinnelsen har differensialtrykkutstyret (4) strømningskanaler (40) som med utgangspunkt i utstyrets midtakse (A), oppviser avtagende diameter (D1 > D2 > D3 > D4) ettersom den radiale posisjon øker (R1 < R2 < R3). I eksempler på utførelser har strømningskanalene (40) innløpsåpninger (41) og/eller utløpsåpninger (42) med nedsenkningsvinkel (a), mens strømningskanalene (40) er konsentrisk anordnet med lik innbyrdes avstand på tverrsnittsoverflaten (Q) av differensialtrykkutstyret (4). Fordelene ligger bl.a. i forhøyning av differensialtrykket ved liten volumstrøm (dV/dt) og senkning av differensialtrykket ved stor volumstrøm, og alt i alt en forbedret linearitet over hele måleområdet i forholdet mellom volumstrømmen (6b) i omføringsledningen (3) og volumstrømmen (6a) i gassledningen (5).
