ABSTRACT:
A hot-wire air flow meter for detecting air flow intake has a main passage (21) and a generally parallel sub-passage (31) for bypassing said main passage, and located in the sub-passage is a hot-wire element (2a) for detecting air flow intake. A dished member (34) is located upstream from an inlet (31a) of the sub-passage, the dished member having a base portion adjacent the sub-passage inlet and an upstream projecting edge (30a) extending from said base portion. The upstream extending edge (30a) at least partially surrounds the inlet (31a) and is located between the sub-passage inlet and the main passage, the effect of the dished member tending to stabilize air flow entering the sub-passage so that the air flow is less affected by bends in pipework upstream from the air flow meter.
