摘要： A device for determining at least one parameter of a medium flowing in a line in a main flow direction includes a part adapted for introduction into the line. The part may include a measuring element for determining the at least one parameter; a measuring channel that may include an inlet, an outlet, a bent first section between the inlet and the measuring element, and a second section into which the first section may transition, the measuring element being located in the second section; and a projection, where a partial stream of the medium may flow in a measuring channel flow direction from the inlet to the outlet, the first section may redirect the partial stream after entering the measuring channel, and the projection may project into the measuring channel at a location downstream from the inlet and upstream from the measuring element relative to the measuring channel flow direction to direct the flow of the partial stream, and counteract a separation of the flow of the partial stream from channel walls of the measuring channel.

摘要： The invention relates to a device for determining at least one parameter of a medium flowing in a line, in particular the intake air mass of an internal combustion engine. The solid particles contained in the line act on a measuring element and influence a characteristic curve behavior of the measuring element, which is used to determine parameters of the flowing medium. In order to reduce the action of solid particles on the measuring element, the measuring element is disposed in a line or a tubular body downstream of a protective screen, and an element for influencing movement paths of the solid particles is disposed in the line, on an inner wall. By intentionally influencing the movement paths of the solid particles, their action on the measuring element is considerably reduced.

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： 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 relates to a device having a sensor carrier, which comprises a sheet-metal element and a plastic element and on which a measuring element introduced into the flowing medium is disposed. The use of plastic, which for the most part covers the sheet-metal element, means closer tolerances, which improve the performance of the sensor carrier both in terms of its facing into the flow and experiencing a flow around it, for instance by providing it with an improved aerodynamic leading edge, or the measuring element can be mounted flush to the surface and flush with edges of a sensor cavern, so that no turbulence occurs in the medium in the region of the measuring element or flow under the measuring element. The sensor region of the measuring element is reliably protected by recesses in the longitudinal edges and by a special adhesive bonding process from a gel emerging from the electronic evaluation circuit, so that the measuring characteristic curve behavior is not altered.

摘要： The match with a measurement characteristic curve of a device for air flow measurement is disturbed by pulsations, soiling and poor flow behavior. An improvement in the measuring performance of the device is achieved by provisions, which are adapted to one another, for reducing these sources of trouble, according to which the flow cross section of an inlet conduit narrows in a flow direction in the inlet conduit toward a deflection conduit, and a peripheral face of a first portion of the deflection conduit is embodied in inclined fashion, and at least one outer face of a sensor carrier, together with a peripheral face, closer to an outlet conduit, of the inlet conduit, forms a flush transition.
