ABSTRACT:
A gas flow directing and restricting device intended for flow measurement and having bilaterally located apertures (2) communicating via a measuring tube (3) to a measuring device (4) for measurement of pressure difference. Starting from aperture (2) and leading towards the inside boundary of flow tube (1), there are one or more baffles (5) either perpendicular to the longitudinal axis of tube (1) or inclined forwards against the direction of flow, whereby said baffles guide the flowing gas to aperture (2).
