摘要： The invention proposes a device for measuring the mass of a flowing medium, in particular the mass of air aspirated by internal combustion engines. The device has a platelike sensor element which is accommodated in a recess of a sensor carrier, and which with a sensor region that has at least one measuring resistor is exposed to the flowing medium in order to measure its mass. The sensor element is accommodated essentially flush in the recess and is retained in the recess by being glued to a bottom face in the recess. The bottom face of the recess of the sensor carrier has a troughlike indentation, which extends at least partially along the circumference of the sensor element outside the sensor region that has the at least one measuring resistor. The device according to the invention is intended to measure the mass of a flowing medium, in particular for measuring the mass of air aspirated by internal combustion engines.

摘要： A mass flow sensor includes a measuring element arranged on a membrane that is clamped in a frame. The sensor is formed by introducing a recess into a silicon wafer. Through the application of a recess having perpendicular walls, the thickness of the frame can be reduced, thus allowing the required surface area of the wafer to also be reduced.

摘要： A device for detecting a pulsating variable, for instance the air flowing in the intake tube of an engine, is disclosed in which the signal processing and the correction of the pulsation error are done in an evaluation device which is a constituent of the sensor. At the output of the signal processor, the sensor, for instance a hot-film air flow rate meter, outputs a corrected output signal, which is directly a measure of the variable to be determined, such as the mass of the air flowing in the intake tube of an internal combustion engine.

摘要： An apparatus for determining the flow rate of a flowing medium having a substrate as a carrier and a resistor arrangement disposed on the substrate which among other elements includes a layer-like measuring resistor (R.sub.H) as well as a likewise layer-like heating resistor (R.sub.S), the heating output of which is regulated such that the measuring resistor (R.sub.H) has a constant temperature, the heating output of the heating resistor (R.sub.S) being a standard for the flow rate of the flowing medium. The surface area of (R.sub.S) is greater than the surface area of (R.sub.H) and extends farther toward a fastening of the substrate, in order to prevent a flow of heat out of the vicinity of the measuring resistor (R.sub.H). The measuring resistor (R.sub.H) and the heating resistor (R.sub.S) are located on the downstream portion of the substrate, on a lip set off by a slit. With this disposition of the measuring resistor (R.sub.H), soiling of the substrate affects the measurement result only slightly.

摘要： The invention is directed to a flow sensor having a heater, two temperature measuring sensors, a heater temperature sensor and a medium temperature sensor. A control circuit is provided which controls the overtemperature of the heater in dependence upon the temperature of the flowing medium. With this arrangement, the influence of the temperature dependency of the following on the sensor characteristic are compensated: viscosity, thermal conductance and thermal capacity of the medium. The relationship between the heater temperature and the temperature of the medium is adjusted in a slightly nonlinear manner by means of special evaluation circuits. In this way, a further improvement of the temperature compensation is obtained.

摘要： A method and apparatus controls the temperature of a precision resistor and, in turn, measures the flow rate of a flowing fluid mass. The precision resistor is a hot wire or hot film of an air mass meter of an internal combustion engine of a motor vehicle. Through timed current flow, the operating temperature of the precision resistor is maintained at a higher temperature than the temperature of the flowing fluid mass. The timing of the electric current for maintaining the operating temperature of the precision resistor is controlled based on the magnitude of the gating voltage supplied to heat the precision resistor.
