Abstract

Massestrømningsmåler for å måle masse og tetthet til et fluid som flyter gjennom et målerør. Massestromningsmåleren bruker Coriolis prinsipp for å etablere masse og tetthet. Massestsrømningsmåleren innbefatter i det minste en, fortrinnsvis to, målerør. Hvert målerør er forsynt med en svingingsgenerator og en første svingingsdetektor og en andre svingingsdetektor. Svingingsgeneratoren er for å bringe målerøret til å svinge og svingingsdetektorene er for å detektere svingingen i målerørene når fluid strømmer gjennom målerørene. Svingingsdetektorene bestående av armatur i form av stavmagneter som strekker seg inn i en ringspole. Spolen er forsynt med en første vikling og en andre vikling, som er forbundet i serie og som er anordnet ved en avstand fra hverandre langs en lengdeakse. Den første viklingen er viklet i en retning rundt en lengdeakse og den andre viklingen er viklet i en annen og i forhold til første vikling en motsatt retning rundt lengdeaksen. Dette betyr at målenøyaktigheten økes og samtidig reduseres kravene til monteringstoleranse.
