    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: 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 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.

    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: 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.
