Abstract

Oppfinnelsen gjelder en fremgangsmåte og anordning for nøyaktig måling av en gassleveranse med en gassmåler. Det er kjent en gassmåler (1) med gjennomstrømningsføler (1a) for bestemmelse av et målesignal for et mengdeforbruk og/eller energiforbruk av gass (3a). Med oppfinnelsen bestemmes det en korreksjonsfaktor (F) ved veid gjennomsnittsberegning av en følerfeilfaktor (fj, fj', fj", fj''') for gassmåleren med en forbruksprofil (lj, lj', Lj) som er karakteristisk for gassleveransestedet (14), og målesignalet (VS, Vns, MS, ES) omregnes med korreksjonsfaktoren (F) til en korrigert forbruks- eller utgangsverdi (Vn, M, E). Gassmåleren kan drives som volum-, masse- eller energimåler og det angis bl.a. formler for bestemmelse av en korreksjonsfaktor med følerfeilfaktorer og forbruksprofiler som gjelder volum, mengde eller energi, og mengdesignalkorreksjon for ikke-registrerende eller registrerende gassmålere. Det oppnås bl.a. retroaktiv, kundespesifikk målesignalkorreksjon, ingen ekstra målekompleksitet i gassmåleren og forbedret målenøyaktighet, særlig forbedret energimåling ved at det kompenseres for iboende svingninger i energisignalet (ES) ved endringer i varmeverdi (Hj, Hj').
