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.

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

A device for measuring the mass of a flowing medium with a temperature-dependent measurement element has a measurement conduit whose faces, which extend perpendicular to a surface fixed by the measurement element, are inclined and approach each other in the flow direction of the medium in the measurement conduit. The invention is provided for measuring the mass of a flowing medium to measure the intake air mass of internal combustion engines.

Devices for measuring at least one parameter of a medium flowing in a line, having an inlet conduit an outlet conduit, having the disadvantage in the prior art that liquids flowing into the inlet conduit can reach a measurement element and alter the measurement characteristic curve behavior of the measurement element. A device of the invention has, between the inlet conduit and outlet conduit, a deflection conduit with a separation element, by which the liquids are separated out and therefore do not reach the measurement element.

A method and device for analyzing and quantifying flows for the three-dimensional determination of flow velocity components or the visualization of flows in fluids or gases. An illuminating device generates electromagnetic radiation of a predefined color to scan a detection space in the form of light planes arranged spatially one behind the other that are at least roughly parallel, and that are generated temporally one after the other. As a result, electromagnetic waves are generated in the detection space by particles characterizing the flow, and are detected using at least one image detector which records two-dimensional color images. The frequency, frequency spectrum, and/or intensity detected by at the least one of the image detectors is changed by an as a function of time.

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.

A method and a device suitable for carrying out the method are proposed for analyzing and quantifying flows, in particular for the three-dimensional determination of flow velocity components or the three-dimensional visualization of flows in fluids or gases. For this purpose, electromagnetic waves, especially light, are detected, which at least partially emanate from or are scattered by particles that are contained in the detection space and that characterize the flow to be analyzed, the waves being detected using at least one detection device, in the form of two-dimensional images that are recorded in a frequency-selective or frequency-band-selective manner, from which the flow is determined. The illuminating device for this purpose generates at least two, at least approximately parallel light sheets, arranged in spatial succession, generated in temporal succession, having electromagnetic waves of different frequencies or different frequency spectrums, which scan the detection space at least in areas.

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 ( ) possesses an axially extending measuring duct ( ), in which a temperature-sensitive measuring element ( ) is accommodated. The measuring duct ( ) extends from the inlet mouth ( ) to a deflecting duct ( ), out of which the flowing medium flows out from an outlet orifice ( ) without any axial distance from the inlet mouth ( ) 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.

Electrical machine, in particular claw pole generator

A method for the quantitative acquisition of flow patterns in fluid flows in which a medium (e.g., a gas or a liquid) and the particles contained therein and carried in the flow are set in motion in a transparent flow object. The method provides that a flow object is transilluminated by a laser light fanned out on a plane parallel to the longitudinal axis of the flow object. A scattering of the laser light by the particles is detected by a camera positioned at a right angle to the longitudinal channel axis and moving in the vertical and horizontal directions, and can be analyzed with an analysis unit connected downstream from the camera. The analysis unit is calibrated by quantitatively comparing an image, which has an object-to-image ratio and which is recorded inside the flow object by the camera, to an image having an object-to-image ratio and recorded outside the flow object.

A method and device for sensing three-dimensional flow structures, which is distinguished in that at least two, preferably three light sheets of a different wavelength or light intensity are produced in a flow measuring field. When a particle carried along by the flow traverses the light sheet, scattered light produced by the particle is optically detected as a particle trace, separately for each light sheet. The detected particle traces of the light sheets are combined into one particle path, and on the basis of the composite particle path, the three velocity components of the flow are calculated.
