ABSTRACT:
In an apparatus for measuring the velocity of flow of fluids, and particularly of the intake air of internal combustion engines, having an electrically heatable resistance layer which is applied in insulated manner on a support and is in thermal contact with the flowing fluid, the support is developed in rectangular shape with a flat central part bearing the resistance layer and is provided with reinforcement strips integral with it on at least three sides. Furthermore, the central part is provided at its edges with slits which adjoin the reinforcement strips. The apparatus of the invention can be produced preferably from silicon by etching and can be developed to receive further resistors and other electronic elements.
