Abstract

Det er beskrevet en fremgangsmåte og anordning for måling av gassforbruk ved hjelp av en gassmåler (1). En gassmåler (1) som har en termisk gjennomstrømningsføler (la) for bestemmelse av mengdestrømsignaler (SM) og kalibrert som energimåleapparat for avgivelse av energiverdisignaler (SE), er kjent. I henhold til oppfinnelsen blir en gassart bestemt av gassmåleren (1) i den grad det skjelnes mellom brennbare og ikke-brennbare gassblandinger (3). For en ikke-brennbar gassblanding (3) drives gassmåleren (1) med kalibrering i masse- eller standardvolumenheter (l/min.), mens for en brennbar gassblanding (3) drives den med kalibrering i energienheter (kWh). Utførelseseksempler gjelder blant annet måling av en gassparameter (?, a, c, ?) for gassen (3) i den hensikt å bestemme gassart, en gasskvalitetsføler (1a) som har samme konstruksjon som den termiske gjennomstrømningsføler (1a), og måleintervaller som forlenges ved en ikkebrennbar gass (3) og forkortes ved en brennbar gass (3). Fordelene ligger blant annet i pålitelig energimåling som følge av automatisk differensiering mellom en ikke-brennbar gass (3) og en høyverdig nyttegass (3), erkjennelse av manipuleringsforsøk og automatisk ettersporing av varmeverdi selv uten måling av varmeverdi.
