Abstract

For virksom ultralyddempning for ultralyd-gassmåler blir det stilt til rådighet en anordning for innbygning i en rørledning som gjennomstrømmes av et gassformig medium. Anordningen består av et i ledningen innførbart hus eller hylster (11) med et strømningsinnløp (12) og et strømningsutløp (13), idet det i huset (l 1) er anordnet parallelt med hverandre hullplater (14) som får tilstrømning frontalt, idet hullplatenes tykkelse er <, 8 mm, og der diameteren av hullene (15) er < 10 mm og ved hvilken avstand (a) for hullplatene (14) utgjør < 10 mm.For effective ultrasonic damping for ultrasonic gas meters, a device is provided for incorporation into a pipeline flowing through a gaseous medium. The device consists of a housing or casing (11) insertable in the conduit having a flow inlet (12) and a flow outlet (13), in which the housing (11) is arranged parallel to each other hole plates (14) which receive frontal flow, thickness is <8 mm, and where the diameter of the holes (15) is <10 mm and at what distance (a) for the hole plates (14) is <10 mm.
