Abstract:
1. An air flow measuring device comprising: a module housing supported cantilever-like in an area where air flow is to be measured, wherein said module housing further comprises: at least one electrical circuit incorporated in a portion thereof; a sub-passage through which at least a part of the air flow to be measured is introduced, said sub-passage having an inlet and an outlet, wherein said sub-passage has a curved portion that deflects part of the air flow; and a flow measuring element located downstream of the curved portion as viewed in the part of the air flow introduced in the sub-passage, with the location of said flow measuring element relative to said curved portion being such that particles in said air flow do not interfere with said flow measuring element, and wherein said flow measuring element is electrically connected to the portion of the module housing where the electrical circuit is incorporated, and, wherein the inlet of the sub-passage is located upstream of the flow measuring element in view of the air-flow, wherein a part of the air-flow is led by the curved portion to the portion of the module housing where the electrical circuit is incorporated.
