<p>The invention relates to a gas flow monitor in which the adjustment of a defined value range of the closed and/or nominal flow rate may be made witho ut interference in the position of the functional elements. Moreover, the ad justment or a change in the closed and/or nominal flow rate that was set sho uld also be possible outside the production site as well. For this purpose, the gas flow monitor comprises a gas-tight housing (1), which has a valve se at (5) for a closing member (9) that is movable in the housing (1), the clos ing member being guided in a longitudinally movable fashion in a sheath (6) via a pin (7) and held in the open position against the flow direction by th e force of a closing spring (11). The housing (1) is connected on the inlet side to a tube-shaped insert (13), the inner contour (14) of which determine s the flow profile up to the valve seat (5).</p> |
