摘要： A device for measuring the mass of a flowing medium, or flow rate meters, having a measuring element accommodated in a measurement support; upstream of the measuring element, a grid with flow openings is provided. To attain a substantially rotational symmetrical velocity distribution even in the case of a severely impeded oncoming flow, the grid has flow openings, which at least regionally have a different flow cross section. The flow cross sections of the flow openings are adapted to the oncoming flow, in order to bring about a flow with substantially even velocity distribution downstream of the grid. The device is intended for measuring the mass of a flowing medium, in particular for measuring the mass of aspirated air in 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： In a method for correcting an output signal of an air mass meter, an air mass aspirated by an internal combustion engine is detected, so that first a characteristic of the air mass meter representing a relationship between an output voltage of the air mass meter and a flow air mass is determined, the characteristic in a region which the air mass can flow back is corrected by changing the characteristic in a return flow region relative to the measured characteristic, the change of the characteristic is performed so that the relationship between the output voltage of the air mass meter and the measured air mass is adjusted to minimize error measurements, and the computations of the aspirated air mass is therefore performed with the aid of the corrected characteristic.

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： 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 for measuring the mass of a medium flowing in a line, especially the aspirated air mass on an internal combustion engine, comprising a flow tube, which is disposed in the line. A measuring element around which the flowing medium flows is disposed in the flow tube. The medium flows from the line into the flow tube at an inlet opening and out of the flow tube into the line at an outlet opening. An outlet end face of the flow tube surrounding the outlet opening has structural grooves, which extend with a radial directional component with respect to a longitudinal axis of the flow tube.

摘要： A device for measuring at least one parameter, in particular of a volumetric flow, of a medium flowing in a line, in particular of the intake air volumetric flow of an internal combustion engine, includes at least one measuring element around which the medium flows. Constrictions, which do not uniformly constrict the cross-section of the line, do not produce any ring-shaped eddies that may be heard in the form of whistling noises.
