Abstract
In air flow rate meters having a substrate body that protrudes into the air intake tube of an internal combustion engine and has openings in which hot wires are deployed over support points, the problem arises of reducing the heat losses caused by the support points. By disposing a frame body (4) on the substrate body (1) and embedding the connection wires (23, 42) and the linking wire (32), all of which have a very small cross section and serve to electrically connect the hot wires (28, 36), the heat losses to the support points (26, 30, 34, 38) can be reduced. The air flow rate meter is suitable for measuring the mass of aspirated air in internal combustion engines.
