<p>An apparatus for measuring the rate of flow of a medium especially for measuring the rate of flow of air inducted through the intake duct by an internal combustion engine comprises at least one temperature-dependent resistor (3) formed as a layer (coating) resistor provided with a dielectric, corrosion-resistant, hydrophobic, pinhole-free protective layer (18) which is as thin as possible. The protective layer (18) comprises an organic substance which is precipitated from the vapour phase by polymerization under the action of energy. <IMAGE></p> |
