摘要： The invention relates to a device for measuring at least one parameter of the intake air mass flow of an internal combustion engine. Fluid particles contained in the line act on a measuring element and influence a characteristic curve behavior of the measuring element used to determine parameters of the flowing medium. In order to reduce the action of fluid on the measuring element, the measuring element is disposed in a line or a tubular body, downstream of a protective screen, which deflects the medium flow and deflects the fluid particles. Downstream of the protective screen, longitudinal ribs, a suction opening, or a turbulence generator reduce the release of uncontrolled eddies.

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： In devices for measuring the mass of aspirated air of an internal combustion engine, for instance, via a line, it is already known to provide a tubular body inside this line and to provide a temperature-dependent measuring element inside the tubular body. In order that dirt particles and liquid droplets entrained by the aspirated air will be kept away from the measuring element, in accordance with the invention, a protective screen is disposed inside the tubular body, upstream of the measuring element; the screen extends in inclined fashion in the flow direction, and dirt particles and liquid droplets are deposited on it and carried to a downstream end of the protective screen, so that via an outflow opening they can reach the inner conduit wall of the tubular body and be made to bypass the measuring element.

摘要： Devices for measuring the mass of a flowing medium using a temperature-sensitive measuring element have the disadvantage that considerable measuring errors may occur in the event of a pulsating flow characterized by flow fluctuations. In order to counteract these measuring errors, the device (1) possesses an axially extending measuring duct (33), in which a temperature-sensitive measuring element (20) is accommodated. The measuring duct (33) extends from the inlet mouth (36) to a deflecting duct (34), out of which the flowing medium flows out from an outlet orifice (46) without any axial distance from the inlet mouth (36) and radially underneath the latter. The invention is provided for measuring the mass of a flowing medium, in particular for measuring the intake air mass of internal combustion engines.

摘要： A device is provided for determining at least one parameter of a medium flowing in a line in a main flow direction, e.g., a parameter of the intake air mass of an internal combustion engine. The device includes a part, which is inserted into the line at a predetermined alignment with respect to the main flow direction in such a way that a partial flow of the medium flowing in the line in the main flow direction flows through at least one measuring channel provided in the part in a first direction from an intake of the measuring channel to an outlet of the measuring channel. The device further includes a measuring element situated in the measuring channel for determining the at least one parameter. Between its intake and its outlet, the measuring channel features at least one channel segment in which a mechanism is located that causes flow vortices in this channel segment, whereby liquid droplets and solid particles are advantageously deposited on the inner wall of the channel before they can reach the measuring element.

摘要： A method for cleaning of a measuring element (1) passed over by a gas flow is arranged on a thin-walled membranous material (5). The measuring element (1) includes at least one heatable element (6, 7, 8; 10, 11), which is arranged on the membranous material, the membranous material being capable of vibrating. By means of a control apparatus (20) or a switching (22) associated with the measuring element, a periodic delivery of current (41, 42) in intervals takes place in this manner to at least one heatable element (6, 7, 8; 10, 11) of the measuring element (1) and thereby produces vibrations. Alternatively, vibrations of the membranous material (5) can be produced by special vibration exciters or by means of ultrasonic coupling.
