Abstract:
1. A device for measuring the volume flow of a gas, whose direction of flow can reverse, the device comprising: an arrangement with a Y-piece with one end of said arrangement connected to a component through which gas flows and in which changing directions of flow may prevail, and with other ends connected with components through which gas flows and in which there is no change in the direction of flow, said Y-piece having separate uncoupled flow paths for gas flows with different directions of flow, which extend in parallel and are separated from one another by a flat partition in the area in which said uncoupled flow paths for gas flows with different directions of flow extend in parallel to one another, with said partition extending to a partition end defining a transition from said gas flows in which changing directions of flow may prevail to said different directions of flow extending in parallel to one another, said arrangement being equipped with means for obtaining measured values to characterize the flowing gas in an area in which different directions of flow extend in parallel to one another.
