Abstract

En fremgangsmåte for måling av en luftstrøm | (qv) i en ventilasjonskanal, i en del (1) av denne, eller ved hjelp av en motsvarende .måleanordning (4), såsom en måleskive, en målering eller en måleflens, hvor måle- anordningen holdes i måleposisjon ved målingen, samt en luftstrømspreder hvor denne fremgangs- : måten anvendes. Ved fremgangsmåten ifølge opp- : finnelsen vris eller flyttes måleanordningen (4) etter målingen av luftstrømmen (q ) til en stilling der den forstyrrer luftstrømmen så lite som mulig samt vris eller flyttes til- bake i målestilling ved en ny måling.A method for measuring an air flow | (qv) in a ventilation duct, in a part (1) thereof, or by means of a corresponding measuring device (4), such as a measuring disc, a measurement or a measuring flange, where the measuring device is held in the measuring position during the measurement, and a air flow diffuser where this procedure is used. In the method according to the invention, the measuring device (4) is rotated or moved after the measurement of the air flow (q) to a position where it interferes with the air flow as little as possible and is rotated or moved back in the measuring position by a new measurement.
