Device for adjustment and measurement of flow in gas-form medium in channel - has straight tube part, at least one branch tube and releasable component for adjustment and measurement of flow through branch tube

摘要

The releasable component (3) incorporates a cover (5) for the one end of the straight tube part (1) and connected to the cover is an inner tube (4) provided with an adjustment opening (6), which by turning and/or axial displacement of the component can be made in varying degree to coincide with the branch tube (2) mouth (7) in the straight tube part (1). The releasable component (3) can have a throttle device (13) for difference pressure measurement, e.g. a measurement flange, with corresp. measurement apertures (14), which are connected with a measurement outlet (16) on the cover (5).
