Abstract: An apparatus for measuring the mass of a flowing medium and a method for producing the apparatus are proposed in which a plate-like carrier on which at least one resistance coating is applied. Continuous fastening openings are provided in the carrier and the resistance coating such that they extend parallel to one another and at the same distance from one edge of the carrier. Rigid electrical connections are inserted through the fastening openings and are soldered provisionally with the resistance coating. A source of current is applied to each of the electrical connections for heating the connections to such an extent that the solder between the electrical connections and the resistance coating melts, causing the carrier located in a steady laminar flow to rotate into a streamlined position. The heating current is then interrupted, and the solder, as it sets, fixes the carrier in this streamlined position at the electrical connections.

Abstract: A temperature-dependent measuring resistor layer is applied to a first carrier, the temperature and/or resistance of which layer is regulated in accordance with the mass of the medium. The first carrier is approximately rectangular and in particular is disposed parallel to the flow direction in a convergent section of the flow cross section. In a parallel section of the flow cross section, a second carrier having a compensating resistor is disposed, which likewise has a rectangular cross section and in particular extends parallel to the flow direction. An arrangement of this kind not only avoids deposits on the end face of the first carrier pointing into the flow but also prevents the result of measurement at the measuring resistor layer from being affected by the position of the second carrier in the flow cross section.

Abstract: An air flow rate meter for ascertaining the mass of the air flowing through an intake tube of an internal combustion engine. The air flow rate meter includes a temperature-dependent measuring resistor, which as a resistance wire is stretched out in an aperture of a carrier body and is disposed, as is a reference resistor, as an element in a common electrical bridge circuit. The carrier body protrudes into a flow cross section through which the air flows, and the reference resistor is wound, in the form of a reference resistor wire, on a partial segment spaced apart from the aperture. A compensating resistor is disposed in the aperture upstream of the measuring resistor and spaced apart as far as possible from the reference resistor.

Abstract: A method is proposed for measuring the flow rate of the pulsating air mass aspirated by an internal combustion engine when there is a backflow. To this end, an integration process in one direction is initiated at a zero passage of the flow rate measurement value (U.sub.S) of the air flow rate measuring device at a given time, which indicates the beginning of the backflow; this integration process is continued until a subsequent zero passage occurs. Directly thereafter, an integration process in the opposite direction is initiated, which is terminated at a time when the latter integration value returns to zero. During the first integration process the flow rate measurement value (U.sub.S) is set to the value of zero and is not deregulated until the termination of the second integration process, so that it then jumps to a value which is subtracted from the flow rate measurement value, and the result is a flow rate measurement value from which the backflow has been excluded.

Abstract: A device for measuring the mass of a flowing medium. The apparatus includes a carrier, to which at least one temperature-dependent resistor layer is applied; on opposing sides this layer is partially overlapped by electrical conductive connecting layers having low electrical resistance and is joined to these layers in an electrically conductive manner. The temperature-dependent resistor layer and the connecting layers are covered with a thin glass layer, except for a respective contact section at each end. Securing sections bent at an angle in the form of claws, each belonging to one electrical connection, are joined in an electrically conductive manner to the contact sections, and the electrical connections are embodied on or joined to holder bodies.

Abstract: A device for measuring the mass of a flowing medium. The device includes a flat carrier to which at least one resistor layer is applied. Electrical conductor connections extending in alignment with one another are fixed on one end, with ends in elastic holder bodies and oriented with ends toward the carrier. On the other end, the ends of the electrical conductor connections rest with support segments each on one end face of the carrier and with fastening segments partially encompassing and gripping the carrier. The fastening segments are soldered or welded to a connecting layer or directly to the temperature-dependent resistor. As a result, the soldered or welded connection is held in a flexion-free and thrust-free manner on the fastening segments.

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.

Abstract: An apparatus for measuring the mass of a flowing medium, in particular, for measuring the aspirated air mass in internal combustion engines. The apparatus includes a flow conduit for the medium, embodied as an air intake tube and having a restricted section, into which a bypass line toward the restricted section discharges at a mouth. In the bypass line there is a temperature-dependent resistor, which ascertains the mass of air flowing via the bypass line, this mass being at a predetermined proportion to that flowing through the flow conduit of the medium, and this resistor via an electronic control unit triggers a fuel-injection valve in the flow conduit of the medium. The course of the flow cross section in the restricted section is determined by way of example by a shaped body surrounding the fuel injection valve.

Abstract: A method is proposed for measuring the throughput of a medium, in particular the air aspirated by an internal combustion engine, in a flow cross section and for correcting the flowthrough measurement value (U.sub.s) furnished by a air flow measuring device in the event of a pulsating flow. To this end, the air flow measurement value (U.sub.s) is modified, in a selected range of the characteristic curve of the air flow measuring device, in such a manner that the error in the air flow measurement value (U.sub.s) resulting from the pulsation of the medium is reduced or compensated for. The range of the characteristic curve selected for modification of the air flow measurement value (U.sub.s) preferably is located below a minimum air flow measurement value (U.sub.sm) characterizing a minimum air flow value (Q.sub.m). In like manner, in order to modify the air flow measurement value (U.sub.s) below the minimum air flow measurement value (U.sub.sm) characterizing the minimum air flow value (Q.sub.

Abstract: A control device is proposed for the burnoff procedure of a hot wire in a constant-temperature anemometer. The control device ascertains temperature increases elapsing in an uncontrolled manner at the hot wire, for instance occurring as a result of a spontaneous ignition of gasoline fumes, and terminates a burnoff procedure, once begun, upon the occurrence of these uncontrolled temperature increases. These events are ascertained via the signal behavior of the hot wire current and are related to a computer-controlled realization and to an analog circuit layout.

Abstract: A method is proposed for measuring the pulsating air mass aspirated by an internal combustion engine in a flow cross section. To this end, an upper reference value (U.sub.or) is determined from the rpm of the engine, above which value a reversed flow of the air takes place, and an actual flowthrough measurement value (U.sub.s) furnished by a flowthrough measuring device is compared with this upper reference value (U.sub.or). Upon the attainment of the upper reference value (U.sub.or) by the actual flowthrough measurement value (U.sub.s), a time period (t.sub.r) begins to run, which ends whenever the actual flowthrough measurement value (U.sub.s) has again dropped down to the upper reference value (U.sub.or). The time period (t.sub.r) is stored in memory and serves in such a manner to correct the flowthrough measurement value (U.sub.s) upon the occurrence of reversed flow that the polarity of the actual flowthrough measurement value (U.sub.s) is reversed, at the most for the time period (t.sub.

Abstract: A method is proposed for the measurement of a medium, in particular of the air aspirated by an internal combustion engine, in a flow cross section and for correcting the flow rate value (q) furnished by a flow rate meter in the event of a pulsating flow. To this end, by measuring the pressure of the medium (p.sub.m) at a restriction and by comparing it with a pressure value (p.sub.s) for steady flow associated with the measured flow rate value (q), the pulsation amplitude (a) is determined and is multiplied via characteristic value memories for the flow rate values (q), in order to correct an average-value error and/or to correct the error in the event of reversed flow, with a correction value (k) in order to form a corrected flow rate value (Q).

Abstract: A air flow rate meter apparatus includes an air bypass line, which branches off from a filter housing on the air intake fitting of an internal combustion engine and discharges at a restriction of the air intake tube upstream of a throttle valve. An injection valve is disposed in the restricted section, ejecting fuel in the direction toward a throttle valve. The air bypass line extends vertically and has a first U-shaped section, the connecting portion of which is located at a lower level than its legs. A temperature-dependent resistor in the form of a hot wire or hot strip is disposed in the downstream leg of the first U-shaped section, so that during a burnoff procedure of the temperature-dependent resistor a flow is effected in the direction toward the mouth of the air bypass line, thus preventing the aspiration of a fuel-air mixture into the air bypass line and thus avoiding the danger of ignition with the possible destruction of the temperature-dependent resistor.
