Abstract
A devices for measuring the mass of a flowing medium, having a temperature-sensitive measuring element, in which accurate medium flow measurement can be made in the presence of a pulsating flow which is characterized by flow fluctuations. In order to provide accurate measurements, the device has a structure which is installed in the measuring conduit in a region of its inside wall upstream and downstream of the measuring element. The structure has friction faces exposed to the oncoming flow in which the friction faces effect a flow resistance which can be varied by the intensity of the flow fluctuations, only in the presence of a pulsating flow, so that the flow is positively displaced more or less into the region of the measuring element, in order to increase the flow velocity and to compensate for the measurement errors. The invention is for measuring the mass of a flowing medium in the intake of an internal combustion engine.
