ABSTRACT:
A flow rate meter including a substrate having at least one temperature-dependent resistor layer applied to it is retained in the flow of a medium by two retaining bodies parallel to one another. These retaining bodies are secured in a base body with a relatively small spacing from one another, which means the base body is not undesirably large in size. The novel flow rate meter permits one to reduce the size of the base body. Beginning at one connecting segment each, which extend parallel to one another, of each retaining body, each retaining body has a securing segment inclined with respect to the other retaining body; the securing segments protrude into the base body, extending directly next to one another. The flow rate meter is suitable in particular for measuring the mass or flow rate of aspirated air int he air intake tube of an internal combustion engine.
