摘要： A measuring device serves to measure the mass of a medium flowing in a line along the primary flow direction, in particular the mass of aspirated air of an internal combustion engine. The measuring device has a measuring element bathed by the flowing medium, which element is disposed in a measurement conduit provided in the line. The conduit extends in an axial direction from an inlet opening of the measurement conduit to a deflection conduit. The deflection conduit leads to an outlet opening that discharges into the line at an outer face of the measuring device. In the surroundings of the outlet opening, at least one protuberance is provided on the outer face of the measuring device that has the outlet opening.

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 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.

摘要： A device for measuring at least one parameter of a medium flowing in a line, in particular the intake air mass of an internal combustion engine in which fluid particles and solid particles in the line influence a characteristic curve behavior of a measuring element which is used to determine a parameter of the flowing medium. A protective screen according to the invention deflects fluids and solid particles away from the measuring element in such a way that they are conveyed against an inner wall of the line. In addition, the device stabilizes the flowing medium by generating longitudinal eddies in a flow direction.

摘要： A measurement device for measuring the mass of a medium flowing in a line along a line longitudinal axis, in particular the intake air mass of an internal combustion engine. The measuring device has a measuring element around which the flowing medium circulates around. The measuring element is disposed in a measurement conduit that is provided in the line and extends along a measurement conduit longitudinal axis from an inlet opening to a deflection conduit. The deflection conduit leads to an outlet opening that feeds back into the line. The measurement conduit longitudinal axis is inclined in relation to the line longitudinal axis by a predetermined angle (&agr;) so that the measurement conduit has a screened region that is disposed outside the parallel projection of the inlet opening along the line longitudinal axis. The measuring element is disposed in the screened region of the measurement conduit.

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.

摘要： A device for measuring the mass of a flowing medium, with a temperature-dependent measurement element that substantially reduces measurement errors due to a pulsating flow that is characterized by means of flow fluctuations. The device has a measurement conduit which extends from an inlet to an outlet that is adjoined by a first section piece of a deflection conduit. The medium flows from the outlet to the first section piece and is deflected by an edge face into a second section piece of the deflection conduit. The edge face of the first section piece of the deflection conduit is embodied as inclined in relation to the flow direction in the measurement conduit. The invention is provided for measuring the mass of a flowing medium, for the intake air mass of internal combustion engines.
