Abstract

Laitteisto ja menetelmä ilmavirtauksen mittaukseen kanavassa, esimerkiksi ilmanvaihtokanavassa (300), joka laitteisto käsittää kanavan yhteyteen sovitettavissa olevan anturin, joka käsittää ultraäänilähettimen ja ainakin kaksi ultraäänivastaanotinta, ja ohjausyksikön, johon ultraäänilähetin ja ultraäänivastaanottimet ovat liitettävissä. Ohjausyksikkö on ilmavirtauksen mittauksen aikana sovitettu mittaamaan ainakin kahden kanavan yhteyteen sovitetun ultraäänivastaanottimen samalla ajanhetkellä vastaanottaman ultraäänisignaalin vaihe-ero ja mitatun vaihe-eron perusteella määrittämään ilman virtausnopeus ja/tai virtaussuunta. Laitteisto on sovitettu suorittamaan laitteiston kalibrointi lähettämällä ultraäänilähettimellä (100) ainakin yksi kalibrointisignaali ja vastaanottamalla kalibrointisignaali ainakin kahdella ultraäänivastaanottimella (102, 104). Laitteisto on edelleen sovitettu analysoimaan vastaanotettu kalibrointisignaali ja analysoinnin perusteella valitsemaan mittauksessa käytettävät parametrit sellaisiksi, joilla parametreilla ainakin yksi kalibrointisignaalin analyysitulos täyttää ennalta määrätyt kriteerit.
