Abstract
An apparatus is proposed to measure the mass of a flowing medium, especially to measure the amount of aspirated air of internal combustion engines. The apparatus consists of an electronic regulating circuit and of a temperature-dependent measuring resistor in the form of a hot wire placed in the medium flow, which is led in the form of a coil around each of the hook-shaped ends of each of the supports. One end of the hot wire, the latter being covered with a thin, electrically insulating layer, is connected with the hook-shaped end in an electrically conducting manner, while the other end of the hot wire is connected with the hook-shaped end of the other support. The closely bundled hot wire coils can be covered with a common protective layer. The supports can serve as electrical connections for the hot wire and are fastened to a carrier.
